Hit on knee cap, swollen and bruised, gets harder to walk due to pain. Should go for x-ray?
A couple of days ago when climbing over a short metal fence, i managed to hit my knee cap with some force on the fence, it immediately came up swollen and bruised instantly, this was several days ago, its still very swollen and bruised and is getting increasingly harder to walk due to pain. Is it worth getting it x-rayed?
