Hey Pix!
Sorry you are having this issue with your PM dr. I have never heard of Percocet or any other opiate exacerbating our condition. Sometimes this type of pain medication is the only thing that helps someone with RSD/CRPS because they cannot tolerate anything else. Many do benefit from the type of meds Russell mentions, unfortunately I am not one of them as I have MANY allergies and cannot take anything in capsule form (pork allergy = no gelatin). Have you tried any of those other non-opiate meds?
I currently take Vicodin when I just can't take the pain anymore. I do not take it often as it gives me a bad headache.
If you have tried and failed all of the other modalities and your dr is gonna take you off something that helps you, then you may need to have a serious chat with her or move on. Do you keep a journal of your pain and how when you take Percocet it helps/reduces it? If not, write down some specific examples to show her so she can see how much it is actually helping you. I would search online how opiates are used in the treatment of RSD/CRPS pain. I googled it and many sites popped up with supporting info. Print something substantial and take it with you to your next appt!
Good luck!!
