Multiple sclerosis (MS) is a chronic disease that damages the nerves in the brain and spinal cord. Sclerosis means scarring; MS sufferers develop scar tissue in response to the nerve damage. Symptoms can include failure of muscle control, balance, vision, and even speech, depending on where the “flare ups” occur. Early MS symptoms include weakness, tingling, numbness, and blurred vision. Muscle stiffness and urinary problems are other signs as well. Treatment can relieve MS symptoms and delay progression, but there is no cure as of yet for MS.
