1.5 years ago: bottom and side of left foot felt asleep a lot

1 yr ago: left arm and leg felt weightless, dizzy, heat flash. Each of the next 4 months same episodes that lasted 20 minutes. Dr. thought TIA. Lesions on right side of brain.

6 months ago: More numbness but now to include up leg. Had multiple Episodes which changed to funny bone feeling in foot, outside calf, inner thigh that lasted for 20 min's, arm = funny bone feeling 2 minutes. (only once did left face tingle for 20 seconds). All on left side, no right

Now: back to beginning, bottom of foot feels numb.

Asking because I get my spinal tap results soon after 3 positive MRI results of legions on the brain. I'll post the results. The longer I walk the better I feel which is the opposite of MS (that I've read). So, maybe there is hope for me.

thanks
