I have suffered from chronic back pain for three years now. I am 31, not overweight, and did not have an injury! I had disc replacement surgury on L4-5 about a year and a half ago with no success. Discography shows that the L5-S1 is not healthy and may be the cause of continued pain. In the past few months I have developed left leg pain and numbness with very bad hip pain as well. This stabbing in my left side (on the back) has just happened and is just aweful when I wake up in the morning. No position helps! Is this a muscle? I can locate it straight away with my left hand reaching back and it hurts to the touch. Any ideas?
