What Are the Symptoms of Multiple Sclerosis?

Remember how I explained that the types of symptoms experienced with Multiple Sclerosis depends on where the lesions (spots on myelin sheath that are damaged) are located? This is a very important concept to understand. Every part of your body is controlled by the brain and spinal cord via a nerve. If the myelin is damaged along a nerve leading from your brain to your hand or if the brain itself has damaged myelin where the hand is ultimately controlled, then your hand won’t function properly (for example). This could mean that you may experience something as mild as a sensory issue or something as severe as a motor issue, it all depends on where the damage is.

The most common symptoms of Multiple Sclerosis are Fatigue, Numbness, Walking (Gait) Issues, Balance  & Coordination Problems, Bladder Dysfunction, Bowel Dysfunction, Vision Problems, Dizziness and Vertigo, Sexual Dysfunction, Pain, Cognitive Dysfunction, Emotional Changes, Depression, and Spasticity. – The National MS Society

Here is a list of various MS symptoms. This does not mean that if you have Multiple Sclerosis you will experience all of these symptoms nor does it mean you can only experience these symptoms, it is just a list of symptoms that can be associated with Multiple Sclerosis in some way shape or form. Some are common and some are a little uncommon. Theoretically, almost any neurological symptom is possible with Multiple Sclerosis but that does not mean it is likely. It is important to not blame everything you experience on Multiple Sclerosis as you can still get sick or injured just the same as anyone else meaning the symptom you are experiencing could possibly be the result of something unrelated to MS. If you are unsure, just ask your doctor!
