I have ankylosing spondylitis which is a disease with no cure. I have been dealing with acute chronic hip and back pain for 10 years. I have been on Percocet 10mg at 4 day. My doctor just switched me 2 oxymorphone 10 at four times a day. I have not been able to Bear the pain on the Percocet tens and I am also on oxycontin 80s for long acting. Does anybody no if the oxymorphone 10 mg should could or would help my horrible pain I have in my spine 24/7? Please help me if you have an answer. I have never done this before or asked for somebody's opinion like this. Does anybody have and answer please?
