I recently injured my back at work last month. I was having upper back pain and was treated with several meds. The upper back pain has left me. After finishing the meds I started getting tingling and radiating down my left leg to my toes. The tingling has not stoped for several week now. I am not having any pain, just tingling or radiating in the left leg. My left leg went out on me for a few seconds while walking a few day ago, but I am ok now. The tingling is more prominent when walking or standing for a log period of time. I was diognosed with arthritis in the lower back several years ago but I do not have any pain. I also had lower back surgery to L4 & 5 disk in 1984. Do you think it is Arthritis related. Maybe the injury agrivated the nerve?
