I've recently experienced a few falls, all of which have transpired quickly. When it happens, I feel as though my leg just isn't there. It's not necessary numb, though my left side has become less sensitive to touch, and it isn't because I've quickly gotten up from a sitting / kneeling position quickly or had my limb fall asleep. I visited my neurologist this morning and he's requesting I have an MRI and EEG next week. He didn't go into full detail, but mentioned possibilities linked to other autoimmune issues, ataxia, or possibily even my migraines. I do experience occasional blurriness, brain fog, vertigo and muscle-burning sensations as well.
