So I'd like to describe what happened I'm 45 and five years ago I started to notice very light tingling in my fingers and toes. However if I focussed on it could be felt everywhere. Would come and go some days would be very light pain. Don't remember when but it's all the time on the tingling. Never stops. Had MRI and various neurological tests. Doctor said everything checked out could not find a reason for what o felt.

Fast forward five years. Have had arm pain along with the tingling. Last month my upper back started hurting. Feels more burning below my shoulders. Doctor thinks it's muscle pain. But I'm not sure. This new issue also comes and goes. Some days doesn't bother me at all. I don't eat or do anything different when it's good or bad. Any ideas?
