... that he should have done 1 injection and if another was needed to wait for 6 months. The pain in my back was so severe afterwards that I had to have a fusion of L4,L5 and S1.The pain in my back and left leg have gotten so severe that I can barely walk. When I had the injections I was laying on my left side. The pain is to the left of my fusion. Is there anyone else that received to many injections at one time?
