Bruised Testicle?

Saturdays MMA class I get a rolling knee bar on someone, done it slightly wrong and put pressure on my left nut. Took a quick rest and thought nothing of it. 12 hours later I notice a little pain. Like the dull pain after being kicked in the nut (I've got two, but only injured one :p). It hasn't really went away, and when I stand up or sit down it gets more painful, then goes back to being dull painful, like 2/10. When I stand up it's more like 6.5/10.



Can you bruise a testicle? Should I ice it? Does anybody have any good jokes on the subject? ;D



Also, I wasn't wearing a cup. I have one I just don't like wearing it as it's awkward and uncomfortable.
