I am currently taking meadone for arthritis in back one knee and sciatica. I also have been having abdominal pain which I thought was GB.. Doc says all looks well. I was wondering how to approach my pain doc about switching med to another like percocet? Allergic to Tylenol w/ codeine and vicodin. Does percocet work for breakthrough pain? And can you even take it w/ methadone? If I have an option I want to get off methadone... Too strong for me especially now that Im having issues with my tummy... Any suggs?
