Hi Ann... welcome to Healing Well. I'm sorry to hear that you're in the same predicament as me. about 12 years ago, I was on a morphine pump after a knee surgery, and like you, I didn't itch or anything but felt horrible... I couldn't wait to get off that stuff.
A friend of mine who is a PA and works for a surgeon writes a lot of prescriptions for pain. He told me that he prescribes a drug called Atarax to counteract allergic reactions to pain meds... you might mention it to your pain doc, although he will hopefully know already what the solution to your problem is. When is your surgery scheduled for? If I don't hear back from you, good luck with your surgery... I hope all goes well and you are able to 'comfortably' control your pain.
