not diabetic. no other drugs. non smoker and don't drink. never get sick... had about 3 common colds in the last 17 yrs... I do have siatic issues and numbness in my left leg... and burning sometimes in my left foot... The Dr. said he is 80-% sure I have MS. they have not touched me yet or done tests. getting apprehensive as I feel this is dragging on and I feel it is serious. I think maybe nerve damage on the S3 or S4 ... my L3 does not look good on an xray I had yesterday at the chiropractor... CT scan at the hospital shows no obstructions. good kidney function.
