Does anyone get relief from fentanyl patch?

My pain management dr suggested the fentanyl patch but im really not sure if its worth trying. Shes already taken me off norco and put me on percocet because i was in intense constant pain with episodes of knee dropping break through pain for 4 days straight. It has helped for the contant pain (i think the break thru pain let up on its own). Then she suggested a low dose patch because it would be longer acting. But im not sure it would be that helpful and i dont even want to be on the narcotics im on now so i dont want anything stronger unless there are definate benefits.

Put in search box…there are some on it,!
