Yeah, I've often wondered about that whole pain thing myself. I've never had tape ripped off my chest before, but I would think it would be painful. But in that article and in the Empire of Dreams documentary, Carrie Fisher didn't seem to be complaining too much about it. She even joked about coming up with a contest to see who would get to rip it off at the end of the day, and she did, in fact, make xerox copies of her... self, and passed them out to the cast and crew. She complained more about the bikini in ROTJ, actually.
