Diclofenac
"I was prescribed this along with tramadol (Ultram) to deal with pain associated with hip and knee arthritis prior to my hip resurfacing procedure.  The combination worked work very well for me although I still needed a cane.  I also got some cortisone injections in my knees which were miraculously helpful.  Since the surgery 1 month ago, I've been able to discontinue the tramadol and now only take the diclofenac occasionally (1 a day, 2-3 x a week). However, it does make me a bit lethargic, and I notice that my legs do swell and I seem to urinate less volume (sorry for the details). I do recommend the diclofenac, however."
