It’s been about 2 months I’m getting tingling and numbness on my left arm. I didn’t go to see my doctor due to my back pain (bulge disk which is ok now). I thought my back bulge disk is causing the numbness of my left arm. Amazingly it only happens half an hour or 45 minutes after my walk. Not when I’m sleeping or working with my pc or any other my activities. Not even when I’m running. I do exercise regularly and I had my annual health checkup which showed my cholesterol level was on the boundary (no medication was given) and no problem with my hearth. I’m 47 healthy male.
Is there any idea what causing this?
