what everyone else said. I have a lot of scarring in my face, neck and shoulder from surgery and rads, and am in fairly constant pain from it. Early on ( 6-8 months post surgery), I talked to the surgeons about the possibility of pain relief through removing some of the existing scar tissue and was told that it "might" help in the short term, but it would simply relocate the problem to a new area.
It is real, it is painful, and it is difficult to manage, especially since often the extensive surgery that we've undergone results in widespread scarring that's further comrpmised with the effects of radiation
