I hope maybe someone out there has some fresh insights. I am 31, and for just over a year now, I have had almost daily numbing in my face, arms, and sometimes both legs at once. I have had multiple MRI's, blood work and 2 spinal taps. So far, they have found 2 nonspecific brain lesions, and they have checked up and down for evidence of MS. More recently, I have suffered 2 concussions from falling when both my legs go numb. I also have concentration and memory problems, as well as right sided weakness. Does anyone know of a possible diagnosis for something like this? Thanks!
