I have similar symptoms to you and I honestly don't know what to think anymore.
8 years ago, I began having some numbness in different parts of the body, had some vision disturbances, but never had weakness nor have I ever fallen or had trouble walking.
Over the years,I began to experience weird symptoms and turns out I had Lyme Disease!! I went through extensive treatment, MS was ruled out because my symptoms didn't match the condition.
But just last week, I began having burning sensation under skin when scratching, in my left side of body; back part of thigh, part of stomach, radiating to my left breast. On top of that, I have tingling in left side of face and leg but these sensations come and go. Appear for a few minutes and disappear for hours.
I know that I have a really bad neck; no curve and it's causing me dizziness and sometimes shaky hands but could all these other symptoms be related to my neck? I'll be seeing a chiropractor soon :/
But I've become so depressed over these past few days, because either my Lyme has returned or I in fact do have MS afterall
