I'm having my first ESI on tuesday. This is 8 weeks after a discectomy and laminectomy. I continued to have lower back pain, leg pain, and hip pain and my new Dr wants to try it since my surgeon that did my surgery never tried any to start with. What can I expect? He is going in on my side since he can't go in on back due to the surgery. Do these injections really fix your dics bulges or what is the real purpose of them?
