Hate to be a party pooper (pun intended) but I had hemorrhoids back in the late 1990's, had them removed via rubber band. It was not painless, although I suppose it was less painful that having them surgically removed. Now 10 or so years later... the are BACK. They really don't bother me too much while riding, it's the after effect that hurts.
They don't always grow back, guess I'm one of the lucky ones.
