I have chronic lower back pain (degenerative disc disease, sciatica, etc) and have been on Norco and Percocet for a little over a year. I'm taking 4 Norco's and 7 Percocets per day. I need to change to something more effective because this is too much Tylenol for my liver. What do my fellow sufferers recommend? I tried Fentanyl and it gave me severe headaches. Tried MS Contin but it caused terrible itching. What else should I try? My pain doctor seems to be out of ideas. I'd like to hear about Methadone? Any others?
