Multiple Sclerosis (MS) is a chronic autoimmune condition in which the body's immune system goes after the myelin sheath that protects the nerve fibers in the central nervous system. This leads to a number of possible symptoms that can change in severity and duration. Some of the more common signs of MS are fatigue, muscle weakness and stiffness, difficulty with coordination and balance, vision problems, and cognitive impairment. Additionally, people with MS may experience bladder and bowel dysfunction, sexual dysfunction, and sensory deficits, such as numbness or tingling in the extremities. The symptoms of MS can fluctuate and be present and disappear at times, and their severity can vary depending on the person and the stage of the disease. It's important to note that MS is a highly individualized condition, and each person's experience with the disease can be unique.
