A study has reported that Viagra given to mice with the animal model of MS showed  staggering results in 50% of the animals.

Daily treatment with Sildenafil (Viagra) rapidy reduced MS-like symptoms so that after 8 days there was an almost complete recovery.

For the first time it was shown how the drug reduced the infiltration of inflammatory cells into the white mattter of the spinal chord. This threrfore reduced the damage to the axons making myelin repair easier for the myelin-making cells.

Recent studies had already pointed to the fact that as well as vasodilation this drug seems to have neroprotective actions so can be used in MS, stroke and Alzheimers.

Researcher are confident that clinical trails in humas will soon be carried out.

Already a study , in the USA , has shown that bloodflow to the brain can be increased in both men and women who have MS using Viagra.

Have you used Viagra and did you find any change in your MS symptoms

Some people with MS may experience a progression of their
symptoms over time. However, the exact mechanisms underlying this progression are not fully understood and it is difficult to predict whose symptoms will worsen and whose will remain stable. The authors of tis report studied a group
of people with MS, with and without clinical signs of motor dysfunction, and agroup of healthy controls, using transcranial magnetic stimulation (TMS).

TMS is a physiological test which measures the damage of
motor pathways of the central nervous system by measuring the speed of nerve
fibre conduction and other related parameters. They found that people with MS had abnormal results in the TMS compared to the controls. The authors also found that people with a higher level of disability had more severe TMS abnormalities. The results demonstrate that TMS may be a useful tool in measuring progression in MS and better understanding the underlying processes responsible for disability in MS.

Doctors don’t have a complete answer yet. In theory, it makes sense that if you limit damage from inflammation, the disease will progress more slowly. Some researchers have even tried using periodic treatments with corticosteroids in hopes of delaying the progression of MS. But so far, there’s little evidence that the approach offers any benefit.

“In general, I believe that steroids hasten recovery and may reduce the risk of future relapses for a time,” neurologist Elliot Frohman, MD, an MS researcher at the University of Texas Southwestern Medical Center, wrote in an email to WebMD. 

But one recent study, called the Optic Neuritis Treatment Trial, found that treating relapses may have little if any effect on the long-term course of MS. Researchers looked at acute relapses that caused optic neuritis. Some patients were given oral prednisone. Others received no treatment at all. Patients in the high-dose prednisone group recovered more quickly from optic neuritis. But a year later, researchers found no difference between the treated and untreated groups in terms of disease progression.

To Treat or Not to Treat

Even when they are untreated, however, acute relapses of MS typically resolve on their own over a matter of days or weeks. For that reason, and because corticosteroids are powerful drugs with some unwanted side effects, doctors may recommend using them only for relapses that significantly affect a patient’s function. Adverse side effects of corticosteroids can include fluid retention, weight gain, elevated blood pressure, and mood swings.

Personally I have found oral steroids to be little or no use as they take so long to take effect that it is impossible to tell if the remission was spontaneous or caused by the steroids. What is you experience of treating a relapse ?

For some people with MS, medicines can provide complete relief from pain,but many pain sufferers do not achieve adequate pain relief by pharmacological means. Fortunately, a number of non-pharmacological approaches can be used that have been proven to be effective in other groups of people with chronic pain.

The biopsychosocial model of pain

The experience of pain is very complex, involving not only the body but also the mind. Current thinking is that chronic pain is best understood from a biopsychosocial perspective, which recognises the importance of the underlying biological basis of pain (for example, nerve damage due to MS), but  also acknowledges that psychosocial factors may have a significant impact on the experience of pain and its effects on life.

Some of these factors include one’s emotional reactions to pain and how one thinks about or deals with pain. The biopsychosocial model has led to treatments that are effective for decreasing pain severity and the negative impact of pain.

People with pain sometimes worry that others think that their pain is “not real”, exaggerated, or a sign of mental illness. On the contrary, chronic pain is a serious condition that is “in one’s head” only because pain signals are processed in the brain. Advances in brain science have confirmed that psychological factors such as one’s emotions or stress can affect physical health, including pain. Living with MS and pain can also cause chronic stress. The brain (mind) and body influence one another in ways that science is just beginning to understand.

Relaxation training

Pain and other stressors often result in a natural response of repeated and prolonged tensing of muscles, which tends to worsen pain. Research has shown that one of the best ways to counteract the tensing effects of pain and stress is to practice various forms of relaxation. There are many methods to achieve relaxation – deep breathing, baths, music, meditation or prayer for example.

Some relaxation strategies can be tried without instruction, whereas others may need to be learned under the guidance of a professional.

People vary in their ability to relax, so trying a variety of relaxation techniques may be necessary to find what works best. Relaxation exercises may also work best when paired with other coping strategies.

Deep breathing is the basis for many relaxation techniques, so it is often a good skill to learn first.

It is generally done lying down or sitting in a comfortable chair. The basic method involves taking a deep breath through the nose, trying to cause a rise in the abdomen, followed by a brief pause, and then exhaling through the mouth. To heighten the sense of relaxation, some people say calming words to themselves, such as “relax” or “peace” on each exhalation. To achieve maximum benefit, deep breathing should be practiced for at least five minutes, several times per day.

Self-hypnosis training

Research published over the past decade supports the benefits of self-hypnosis training for helping individuals better manage both acute and chronic pain. Like relaxation training, self-hypnosis is a way to use the power of the mind to manage pain by altering the experience of pain.

This may include distracting from pain, focusing on more pleasant sensations, or even experiencing pain as decreasing or going away. Contrary to how hypnosis is portrayed in the media, people using self-hypnosis always remain in control of themselves. Training in self-hypnosis should be done with a professional experienced in its use for pain. It can often be learned in only a few sessions and should be practiced regularly to maintain benefits.

Like medications, self-hypnosis training rarely, if ever, eliminates pain completely; nor does it benefit everyone who tries it. However, there appears to be a subgroup of individuals, including those with MS, who report substantial decreases in pain severity following self-hypnosis treatment and who are able to maintain this improvement over time. In addition, unlike some medications, the “side-effects” of self-hypnosis training are positive. For example, in a study that included people with MS, 40 different benefits of self-hypnosis were identified in addition to pain relief and no negative effects were reported.

Cognitive behavioural therapy

Numerous studies indicate that the way people think can have a big impact on how much pain they experience, how they deal with pain, and how much pain interferes with their lives and functioning. Things people do to cope with their pain can also be helpful (for example, using relaxation techniques) or unhelpful (for example, using alcohol excessively to relieve pain).

Cognitive behavioural therapy (CBT) involves teaching people how to change their pain-related thoughts and behaviours in order to reduce pain and its associated suffering. In CBT, individuals are taught to examine the thoughts they have about pain, determine whether these thoughts are helpful or unhelpful, and replace any unhelpful thoughts with helpful, reassuring ones.

CBT often also includes teaching other pain management techniques such as relaxation training, distraction techniques, or activity scheduling. It typically involves either group or individual treatment by a professional with expertise in CBT, and optimally, pain.

Other psychological interventions

Other psychological treatments may be useful in addressing pain and its impact, including support groups, pain education, and psychotherapy. Treating depression, when present, is recommended, given that depression and pain often impact one another. Physical exercise (for example, walking, swimming, or yoga) often has beneficial effects not only on a person’s physical condition but also on pain and stress.

How to find help

Unfortunately, many people with MS pain are offered these treatments only after all medical treatments have been tried and failed. Psychological interventions should be considered early, soon after the development of pain, along with other appropriate and effective treatments such as medications or rehabilitation. The sooner these treatments are used, the more likely they are to be of benefit. For those who do not have access to specialists in the psychological treatment of pain, text and web-based resources may be available from your national MS society, or via your nurse or doctor.

Did you know that double vision can be monocular(continue if one eye covered), binocular (stops if either eye covered) , vertical or horizontal

People with vertical diplopia complain of seeing two diagonally displaced images, one on top of the other. In horizontal diplopia the images appear side by side.

Here are a few facts about MS eye problems

A lot of the pain in MS is due to immobility or poor posture, rather than directly related to damage to the nervous system. In particular, using the same posture repeatedly with mobility aids (e.g. a frame or wheelchair) will put stress on your body, which can cause pain. A physiotherapist can provide useful guidance in this area.

Non-medical approaches to pain management include massage, hydrotherapy, acupuncture and reflexology. However, these activities should be discussed with your doctor beforehand.

Then there are::-

• relaxation techniques,
• meditation,
• prayer,
• breathing techniques,
• self hypnosis
• and psychological interventions such as psychotherapy.

The most important thing is to get pain treated. You should discuss where and how much pain you have with your healthcare provider. Your own description of the pain is the most important aspect of pain assessment.

Unfortunately, knowing how something feels does not mean it is easy to describe. Health professionals often talk about pain being ‘acute’ (short-term) or ‘chronic’ (long-term). But describing how it affects you will be an individual thing. When you do describe it, use whatever words seem to best sum up what you experience, however odd they may seem at first. Here are just some of the words people use to describe pain:

• squeezing or crushing

• cold

• hot or burning

• sharp

• dull

• like ants under my skin or ‘creepy crawlies’

• like a build up of pressure

• stabbing

• creeping

• like an electric shock

Being able to explain your pain also helps family, friends and carers understand this ‘invisible symptom.’

So let’s look at some of the types of secondary pain in MS

Musculoskeletal Pain

Description

Stiff joints and muscle contractures, caused by the physical stress of immobility. It can affect the neck, the back or limb joints.

Non medical treatments

Stretching exercises, posture & gait examination, orthotics, exercise

(Especially swimming), position changes, support and cushioning, application of heat and cold.

Usual medications

Ibuprofen, diclofenac  and naproxen.

Nerve Pressure Pain

Description

Pain caused by pressure on the nerves from immobility or poor posture.

This can include sciatic nerve pain from pressure on the back of the leg and ulnar nerve pain from pressure on the elbow.

Usual treatment

Correct seating is important, but elevation of the legs will usually relieve pressure pain.

Back Pain

Description

This can be caused by muscle weakness, abnormal posture, spasticity and spasm. It may also occur as a result of osteoporosis or MS lesions in the spinal cord. If the osteoporosis was steroid induced changing treatment options often eliminates the pain

Usual treatment

Evaluation to pinpoint the source of the pain is essential, as treatments differ widely. It is also important to note that back pain is not always related to MS even though we all think that all of our symptoms must stem from it.

Pain from MS symptoms and treatments

Description

It is worth remembering that certain drug treatments can have painful side effects. Some people taking beta interferon, for example, experience headaches and flu-like symptoms such as aching muscles, particularly in the first few months of taking the drug. Ibuprofen and paracetamol can both help control these side effects.

Some people taking Copaxone (glatiramer acetate) notice an uncomfortable feeling of tightness or pain around the chest.

Some MS symptoms can cause pain as well as the symptom itself, such as pressure sores, urinary retention and infections. A particular example is pain due to Optic Neuritis—an MS symptom that occurs when the optic nerve is stretched or inflamed (with pain occurring behind the eyes which is intensified with eye movement). Painful optic neuritis is probably a unique kind of pain. In addition to pain, optic neuritis can be accompanied by blurred vision, visual acuity loss, impaired colour vision and complete or partial loss of vision. This was one of my first symptoms although I have fortunately never lost total sight. The painful eye movement did however make it almost impossible to reverse the car wherein I had to look over my shoulder. I also did not seek help tp have this treated but Corticosteroids (oral prednisone and intravenous methylprednisolone) can significantly increase the rate of recovery from optic neuritis.

It is also treated with painkillers like ibuprofen, diclofenac or naproxen.

People with MS can also experience pain as a result of treatment

for the condition. Two examples include injection-site reactions and steroid-induced osteoporosis.

Usual treatment

It is very important to discuss each particular problem with your healthcare provider. Fortunately, fixing the initial problem or changing treatment options often eliminates the pain.

For injections site reactions there are a number of things you can do.

If you get lumps post-injection then try a warming (not hot) pad pre-injection to loosen the sub-coetaneous fat. If the lumps persist then gently massage the area but if the lump develops a discharge contact your doctor as it is possible it has become infected.

If you experience itching or stinging then try using an ice pack for a short period of time before and after the injection. If this does not work, discuss it with your doctor as you may need an antihistamine.

For simple redness and inflammation that lasts more than 24hours you could try using a a cream or gel such as Aloe Vera, Witch Hazel or Arnica but do noit try any other opver the counter cream without discussing with your doctor.

Always let the medication warm up to room temperature before injecting and if you’re using an Autoject the setting should be adjusted based on the depth of subcutaneous tissue in the area you plan to use.

Generally these reactions diminish as you become accustomed to injecting and remember to do it at the prescribed interval without missing a dose.

Interestingly the most common areas for this type of pain are the face, neck
and torso so let’s start at the top with TGN

Trigeminal Neuralgia 

TGN is an excruciating, sharp, shock-like pain in one side of the face, lasting seconds to minutes and often repeated; may be triggered by speaking or a touch. It usually settles spontaneously by itself over several weeks. Unfortunately many of the side effects of the usual drugs mimic the symptoms experienced in MS anyway so it is difficult to tell the cause and it may lead to alarm that the disease is getting worse. To allay these fears I have outlined the usual side effects of each drug,

Usual medications

Carbamazepine (anticonvulsant): Side effects Drowsiness, Dizziness, Coordination difficulties

Phenytoin (anticonvulsant): Side effects Dizziness, Nausea, Insomnia, Uncontrollable eye movements, Coordination difficulties, Slurred speech, Confusion

Baclofen (muscle relaxant): Side effects Weakness, Drowsiness, Dizziness

Gabapentin (anticonvulsant) may also help: Side effects Dizziness, Coordination difficulties, Fatigue

Lhermite’s Sign/Symptom

This is a brief, stabbing, shock-like sensation that runs from the back of the head down the spine, (like an electric shock) brought on by bending the neck forward. It is not always painful.

Usual medications
Carbamazepine or Phenytoin (see above)

Other treatments
A soft collar may limit neck movement. Most often Lhermite’s symptom disappears spontaneously and medical treatment is not necessary.

Tonic Spasms

These, known as spasticity are sudden and painful muscle contractions, producing stiffness of the whole limb, which can last up to two minutes.

Usual medications
Carbamazepine, phenytoin, and baclofen (see above) and
Clonazepam (anticonvulsant): side effects Sedation, Dizziness

Dysaesthetic Pain in Limbs and Trunk

Dysaesthetic means any impairment of the senses especially the sense of touch
This is a condition in which light physical contact of the skin causes pain; Such as the weight of sheets in bed. It involves a persistent burning, tingling, tightness, or aching which may be worse at night and after exercise It may be aggravated by temperature and weather.
Patients frequently state that dysaesthetic burning corresponds with what they imagine a hell might be like. Some of the descriptions given by patients include:
- “Like Hell’s hottest knives tearing at my flesh”
- “Like my flesh is being consumed in a fire”
- “Like my flesh is being torn from my body”
- “Like my flesh has been burned off”
- “A pain worse than pain”
- “Indescribable burning”
- “Like an alien pain monster has taken over my body and has ignited my flesh”

Usual medications
Nortriptyline and amitriptyline.(anti-depressants): side effects Dry mouth, Blurred vision, Sedation, Urinary retention
Gabapentin, (see above)
Tegretol (Carbamazepine – see above) and Epilim (sodium valproate) may also be useful.
Side effects of Epilim nausea, diarrhoea, increased appetite and weight gain, shaky movements, tremor, drowsiness, confusion, temporary hair loss

Other treatments
• Application of cold, pressure stockings
• Capsaicin ointment/cream. Capsaicin is the active ingredient in chilli peppers. It’s what gives chilli peppers their kick. When it is applied to the skin, capsaicin cream has been found to deplete substance P— a neurochemical that transmits pain—which desensitizes a person to pain. Capsaicin cream produces a temporary reduction in pain, so it must be used regularly to provide prolonged pain relief.

Capsaicin can cause an intense burning feeling when it is applied, particularly if it is used less than 3-4 times a day, or if it is applied just after taking a hot bath or shower. However, this side-effect tends to ease off with regular use. Capsaicin cream should not be applied to broken or inflamed skin. Wash your hands immediately after applying capsaicin cream.

In my next article I will be discussing secondary pain in MS.

Although MS pain was first recognised in the 1800s, it was not until the 1980s that the incidence, prevalence and characteristics of MS pain were described.

The severity or frequency of pain varies from person to person. It cannot be predicted by a person’s age, gender, or type of MS. However, the longer someone has had MS, the more likely they are to experience pain as one of their symptoms.

The most common pain syndromes experienced with MS include:

● headache (seen more in MS than the general population)
● continuous burning pain in the extremities
● back pain
● painful tonic spasms (a cramping, pulling pain)

Why does pain occur in MS?

Pain is a sensory symptom directly related to two occurrences – the disruption of central nervous system myelin and the effects of disability.

In other words pain may be directly related to the disease itself (e.g. pain associated with nerve damage), or it may develop because of other MS problems (e.g. pain caused by painful muscle contractions and stiffened joints). Fortunately, most pain in MS can be treated.

When pain is the result of a disruption or alteration of nerve conduction, it is termed neurogenic or neuropathic. Pain caused by nerve damage can range from a mild prickling to severe burning, itching or aching and usually requires different treatment from musculoskeletal pain. In some chronic pain conditions, the constant barrage of pain signals may overwhelm the central nervous system so much that normal sensations such as the stroke of a hand can trigger pain.

Neurogenic pain

Neurogenic pain is described in varying degrees of severity and can be split into two types:
• Continuous and steady
• Spontaneous and intermittent,

One large North American study found that half of those reporting pain said their pain was continuous and severe.

Intermittent, spontaneous pain is characterised as shooting, stabbing, electric shock-like, or searing and is often evoked by stimuli that normally do not cause pain, for example touch, the weight of bed covers, chewing or a cold breeze

Steady neurogenic pain is typified by burning, tingling, tight or band-like sensations, aching and throbbing. This type of pain is often worse at night, worse during temperature change and worsened by exercise.

Then there is tissue damage which may result from disability. This can be secondary to musculoskeletal changes in MS due to weakness or incorrect posture for example. If a person walks in a different way than normal then joints may be stressed and become painful as well.

How can MS pain be treated?

Pain management is approached medically, behaviourally, physically and in some cases, surgically. If it is treated with drugs it is always a balance of risk versus benefit. In other words, medication side effects need to be considered and continually evaluated in terms of their impact on a person’s quality of life.

It is not the remit of this article to identify the drugs used.

Emotional Effects

It is important to recognise the emotional effects of experiencing pain and to develop healthy coping strategies.

Some examples are:

• Learn relaxation and meditation skills.
• Concentrate on positive thoughts and activities.
• Talk to a counsellor.
• Seek assistance from an MS Society Field Worker or an MS nurse.
• Contact a support group for people with chronic pain.

In addition some suggestions for managing pain include:

• Exercising gently and regularly, but only within your limits.
• Modifying your environment (e.g. comfortable bedding).
• Considering equipment that may prevent pain from being triggered (e.g. a gripping stick to avoid having to reach).
• Treating flare-ups as they occur – delay can cause problems.
• Seeing a physiotherapist regularly.

In future articles I will address the current options in treatment of MS pain

MS may be accompanied by a variety of emotional reactions and people with MS face some very special challenges. However, like everyone else, they are trying to do their best to cope with what life has sent them. In most instances, they cope very well and often are stronger for having met these challenges.

Cognition
The areas of cognitive functioning that are most commonly affected in MS include the following:

• Memory
• Visual spatial abilities
• Attention and concentration
• Word-finding
• Speed of information processing
• Abstract reasoning and problem solving

Typically, MS affects some cognitive functions but leaves others relatively intact. For this reason, MS is not likely to lead to the sort of global cognitive decline seen in Alzheimer’s disease. People with Alzheimers, for example, have difficulty storing information from moment to moment. People with MS tend to have a difficulty with retrieving that information. But as MS can affect any part of the brain, almost any cognitive function can be impaired. In some cases, MS-related cognitive changes can be very pervasive, rendering the individual unable to deal adequately with day-today tasks.

There are some common misunderstandings about cognitive dysfunction in MS and the following is by way of reassurance :
• MS does not equal Dementia (as mentioned above)
• MS does not mean that intelligence has declined.
• MS is not a mental illness (although some people with MS experience depression, and this requires medical and psychiatric treatment).
• Cognitive functioning can be assessed
• Cognitive problems can occur at any level of physical disability

Cognitive changes can have a significant impact on one’s ability to live and work. Family members are often unaware that MS can cause cognitive problems and this misunderstanding can result in anger and confusion.

Many factors will determine your response to cognitive problems, including the impact of the disability on your normal way of life, previous ways of coping, and the support you receive from others. You and your carers should remain vigilant as to cognitive changes and if this happens it is wise to obtain a professional evaluation to clarify the nature and cause of the problems.

What can you do?

The health professionals who can help are neuropsychologists, occupational therapists, and speech language therapists. Keep this in mind as often input is needed from a professional trained to assess and treat people with cognitive problems.

As the impact of cognitive changes can be stressful, it may also be helpful to talk to a counsellor or your doctor about how you are feeling.

Hints and tips

• Keeping to a routine is important, as is being consistent. For example, when you open the door to your house, put your keys in the same place every time.
• It might help to get an ‘organiser’. Set it up with sections for everything that affects your day-to-day living. Sections for appointments, for phone numbers, addresses etc.
• Using mental pictures or images to remember something can be a good technique to aid memory.
• Having people repeat or write down instructions often helps. It is important that the person conveying the message, instructions or directions to you knows that you have understood. Repeat it back to the person, and ask for clarification if necessary.
• Keep your mind as active as possible. Reading, doing crosswords and puzzles are good ways of keeping mentally challenged, and it is best to find activities that suit you. However, you do need to be aware of your energy levels and be careful not to tire yourself out.
• Regular rests to recharge your brain (and body) become important when you have MS. Use energy conservation and work simplification techniques to ensure the best possible use of your physical and mental energy. Be aware of and alert for mental fatigue (a decline in cognitive performance following a task requiring continuous mental effort).
• It is also best to avoid noisy and/or distracting environments as these can make it difficult to concentrate.
• It is also important when learning a new task that you allow plenty of time to learn it. If you are having trouble, shift your attention to another task and come back to it later.

It is important that you know that you are not going crazy, that many people with MS experience similar problems with their thinking and memory. In particular, it is important for friends and family members to be aware of the relationship between MS and cognitive dysfunction.
