You have been diagnosed with multiple sclerosis (MS). This is a disease of the brain, the spinal cord, or both. MS destroys the covering (myelin sheath) of the nerves. When the nerves are damaged, messages can't travel to and from the brain as fast or at all. As a result, you may not be able to move your body as well as you did before. You may lose some of your ability to feel things, such as heat or cold. Some people may have vision problems or trouble emptying their bladder. Here are things you can do to feel better.
