I've been on the 25 mcg for 3 years, due to severe back pain, well above 10 on 10 being high pain, total back fusion in 1972, scoliosis, blown disk at last mobile vertibra before pelvic bone. some stinosis, scoliosis curvature is 96% upper and 97 degree lower. ribs compressed left chest to point heart is not where it belongs, when walking I'm dragging my left foot like I'm club footed. what is the best answer for my condition... with fentanyl patch I can work and keep insurance, without it, I'm confined to bed severe pain. is there another drug that works this well without the withdrawals I'm reading about...
