I have received multiple epidural injections in my lower lumbar L5/S1. During the last two injections, I felt extreme nerve pain in my left buttocks and going down the nerve of the back of my left leg. Hot, fiery pain that I almost yelled out during the short process it hurt so bad. Doctor claimed this is normal. I have never had it happen before during the first three injections I received. Has anyone else experienced this? I came home with less bone on bone back pain and instead achey sciatica pain. It has dulled on day two but is still noticeable.
