From oxycontin 20 mg with oxycodone 15 mg two times a day for by pain to Fentanyl 25 mg with 10 mg Norco for by pain. It was working great thru 4 patches ... now my back hurts so much I can Hardy move. I'm thinking about slapping another, my last patch on with 12 more hours to go on my old one. I see my pain doc tomorrow. Any suggestions to ease up the pain in my freaking BACK?
