You ask what seems like a very simple question. The simple answer is “Yes!” but the worst was over quickly. The real answer is more complicated. The physical effect was painful enough but the stressful situation and the feeling that it was out of your control made it seem much worse than it probably was.
I once said that the pain from being hit with a cane was a bit like being struck by a cricket ball. Someone wiser than me asked whether I would be so flippant if I knew the bowler was intentionally aiming at me on every ball in an over!
