Hi everyone. I saw my pain mgmt doc today and he switched me from Oxycontin 30mg to Fentanyl patch 25mcg. I am VERY nervous about the change. I am wondering 2 things. Will the relief be comparable? Can anyone give me advice about which brand works best before I get them filled? I am also concerned that they won't last the full 72 hours. Please, any feedback? Thanks my friends. Hope everyone is having a good day. Hugs -Terri-
