Tingling in left leg after long walk i'm 49 started last year only when walk alot?

Leg tingling: Two things to look for here would be circulation problem with artery blockage or a likely nerve impingement caused by spinal stenosis or a bulging disc pressing on a nerve root at the lower spinal area. Your physician can check for artery blockage and then order a neurology consultation or an MRI of your lumbar spine depending upon his/her findings after a history and physical examination.
