I know the kinda thing you mean, that doesn't sound like the same kind of pain that was mentioned though.
In all reality, you've probably just strained or pulled a muscle, and I'd suggest taking some iBuprofen over paracemtemol (sp? :S) as iBuprofen also contains an anti-inflamitory.
Avoid swimming/exercise for a few days, then just take it easy.
