Multiple Sclerosis (MS) - Symptoms

The symptoms of multiple sclerosis (MS) vary from person to person depending on which parts of the brain or spinal cord (central nervous system) are damaged. The loss of myelin and scarring caused by MS can affect any part of the central nervous system. Myelin is the insulating coating around a nerve.

Symptoms may come and go or become more or less severe from day to day or, in rare cases, from hour to hour. Symptoms may become worse with increased body temperature or after a viral infection.
