Your husband should not have that much pain. I absolutely LOVE Fentanyl. I used it for burns I was told were the worst ever seen post rad. However, with those patches, I felt NO pain at all. It took weeks for the burns to heal and those patches let me get on with my iife as my energy returned. This was before the generics surfaced, so that may be a difference. DO call the nurse/doc for pain relief. When one is in pain, one does not heal well.
