Sure it may suck at first, but the great thing about the human body is the ability to cope with pain. Especially if you can't help it.
After a while we get used to it and it will only improve after that.
On one hand, you'd have gotten somewhat used to the pain and on the other hand you'll only feel better each day. It's a win-win situation (well, apart from getting the pain in the first place of course)

Maybe a few people could do it, but I think most can't.
