Hello; I have had at least 4 surgerys on my back, the L4L5 or vicversa. But I'm still having a lot of pain, Then one morning, my left leg was so sore I could barely walk. I fort to say I also have a modgual on my spine, but can't turn it on because of the pain in my left leg. I'm also take, 100mlgs of the Fentanel, and take 24mlgs of Morphine pills. They help a little to none for the pain.I can't walk for long periods at a time. 45 minutes the most. i'm suffering really bad. can you help me? do I have someother other than what I have disscribe.
