MS symptoms range from mild to severe. It depends on what part of the brain, spine, or nerves in the eyes have been affected. Problems may last for a few days or be lasting. They may also get better and then come back months to years after they start. Some people may have problems that get better and then have lasting harm that is found during an exam.
