I have been through cancer in 2007 and a broken back with a cut spinal cord injury. I have had three surguries on my back so far. I also have necrosis in my left hip causing me pain. My Doctor has me on 150mcg fentenayl and 10.325 norco for pain break through. My question is what else can I take other than the Fentenyal? I am happy with it, but after 1 year of being on it, it seems like I need more and they don't last 72 hours. I am going in for a pain consult with my doctor Wednesday. Can anyone help?
