What causes primary symptoms of multiple sclerosis?

ANSWER

Primary symptoms come from damage to the protective sheath (myelin) around the nerves in your spine or brain. The damage causes scarring, which makes it harder for signals to travel between the brain and the body.

This process can lead to bladder or bowel problems, loss of balance, numbness, paralysis, tingling, tremors, vision problems, or weakness.

Medications, physical therapy, and other treatments can keep many of these problems under control.
