Need advice on pain meds

[CherylS]

An earlier thread about bone and joint pain from Herceptin got a discussion going about pain meds. I am finding myself taking 1-2 Vicodin pretty much daily, later in the day when pain starts to take over. It is primarily in my back and I believe mostly from tissue expanders. What concerns me is knowing that pain meds that contain Acetaminephon cause a depletion in glutathione which can weaken the immune system and cause cancer. Percocet knocks me out, and Darvocet does nothing for the pain. Vicodin is the only one that works and my onc says it is safe. I am taking Whey protein and NAC to keep glutathione levels up, but this daily pain med still worries me, yet I can't feel very good without it right now. Anyone to validate or calm my fears? An Atavan now and then helps with muscle spasms too I think. Thanks in advance. There is so much knowledge on this board.
