Abrown176 I too am on Norco/325 and when ever I've had a surgery or even a flare up, my temperature always goes up, at first they thought I must have had an infection, but as time goes on they realized it probably was the RSD. I've had this crap since 1986 and I still get a temperature when I flare. I dont think the Norco helps, because they give me tylenol, they even give it to me when I have to go to hospital [yuck] I definatly would call one of you're Dr.,s , Don't let it go any longer. Thinking of you. Your new friend Wendy
