The main symptoms of multiple sclerosis include fatigue and pain, according to the National Multiple Sclerosis Society. Around 80 percent of people experience fatigue, which severely hampers their ability to function normally, and up to 55 percent of people experience pain that is "clinically significant."
Other common symptoms of MS include bladder and bowel problems, according to the National Multiple Sclerosis Society. While most people with MS experience bladder problems, following dietary guidelines, taking appropriate medicine and managing fluid intake usually allows patients to manage symptoms successfully. The same is true of bowel problems, which individuals can manage through similar means and through physical activity.
Vision problems are also common in people with MS, states the National Multiple Sclerosis Society. Oftentimes, blurred vision, poor color contrast, and pain when moving the eye are the first symptoms of MS, and anyone experiencing these problems should visit the doctor as soon as possible. Many people also experience cognitive symptoms from MS. In as many as 50 percent of sufferers, the disease damages the ability to learn and remember information and impacts organizational skills and the ability to focus attention and perceive the environment. Additionally, people with MS may experience vertigo or dizziness and have problems keeping their balance.
