Ulrike, I don't know how common this reaction is, but it certainly happens. Happened to a friend of mine; she couldn't stand to wear any clothes at all from the waist up for awhile... luckily she was retired and could stay home. So yes, I've heard of this happening. I believe the medical pros are right- they can avoid irradiating that area for the last week, and yes, it'll heal. Sorry you had such a bad reaction- on top of all the rest of your treatment, you must feel like you're going theough the Seven Plagues! Hope things go well for you as you get through this active treatment phase and move into drug therapy, or wherever you go next. Best of luck - PJH
