While a MS rash can be a symptom of the chronic neurological disease, it is rare.  It is far more likely that the multiple sclerosis rash is actually caused by a medication that is being taken to treat the symptoms of the disease or to slow the progression of the demyelination process going on inside the body.  There are many different multiple sclerosis treatment medications that have rashes or itching as a possible side effect.  If a person begins to experience these after they start a new medication, it is very important to discuss it with a medical professional as soon as possible.

A rash may go away on its own once a body gets used to the new medication that has entered the body.  However, it is important to monitor the rash to make sure it does not get any worse or lead to other symptoms.  If the rash is a constant problem or if it does not get any better on its own, it may be more beneficial to switch to a different medication instead.  Your doctor will be able to recommend a similar medication that will work the same against multiple sclerosis, but hopefully without the having the same side effects.


Other Causes of MS Rash


There are many other speculations out there for why a multiple sclerosis rash could be caused.  One reason is because of a person’s diet.  Many people seem to believe that people with multiple sclerosis are more prone to have problems digesting things like sugar, wheat, or dairy.  For this reason, many people with multiple sclerosis are tested for various food allergies.  They may also try to alter their diet, either on their own or under the guidance of a nutritionist or a registered dietitian.  Some people have noticed that by eliminating certain types of food from their regular diet, they no longer have rashes, dry skin, or itching.  It can be a long trial and error process to discover which type of food is causing the problem, however.

Some medical professionals do believe that a rash can be a symptom of multiple sclerosis due to the fact that it is an autoimmune disease.  The process of demyelination going on in the body could signal it to cause a rash and itching.   However, not much research has gone into this theory, so it has not been proven at this time.
