You know, hon, there are many other different kinds of pain meds to be had. (I'm an old nurse and I know this!) Just give your doctor a call and get something else ordered. There is no reason for you to be in pain, when there are remedies for it - and you will be able to move so much better if the pain is under control. Good luck. Of course, I'm writing this pre-op, and I"m scared to death. Deb
