I know that everybody raced off to Amazon and bought a laminated copy of your Central Nervous System (CNS) chart. "YOU" are appropriately confused and amazed by it, I hope. "YOU" also know from your research that this is what ms in all its forms attacks.
Now the fun part where "YOU" get to smile smugly, trace your finger from where "YOU" are hurting back to your brain and say "oh I understand it is ms." "YOU" also know of a thing called invisible symptoms, and there are things that Magnetic Resonance Imaging (MRI) does not see. That strange tingling that constricting bear hug, that aggravating itch is most likely ms playing its game with your body.
Not everything is ms. Sometimes your bad habits can lead to other illness be aware of this. But, and I stress, but ms has a very large field to mess with and it will and can do all sorts of things. Live your life aware and try not to be too surprised with what happens to "YOU."
ms is a lifelong condition with a large playing field, and a determined "YOU" taking your Disease-Modifying Therapy (DMT) messing with its machinations.
ms is doable illness, and you will survive by being smart about it
