I have degenerative disc for 10 yrs. I also have degenerative spondylolisthesis almost at grade two. Last week I believe I put my back out but can't remember how! I have tried ice, heat and hot tub. I also take alot of pain medication for chronic pain. The acute pain that I experience now is unreal. It hurts to brealth, cough and move. Have tried exercise but the pain is too great so I stopped. Any suggestions please write.
