I had a cauliflower ear last week. If you don't know what that is look it up, it's pretty common among rugby players and wrestlers. Anyway it was all swollen nothing to serious so I had it drained. The funny bit is that I had to put a bit of cotton wool on my ear held on by a clothes peg for the day, I got laughed at by strangers. Then the next day I played in a match and got concussed. It was ok I walked it off but god was I confused for a while.
