To enter or not, hmmm

Hey guys, I've got a big competition next week and I really wanna enter it, the only thing is over the past week or so i've developed a knee injury. Not sure what it is but my knees are very cracky, will a dull ache and swollen, I'm on ibuprofen at the mo and using glucosamine gel but its not getting any better, not sure whether i should risk entering or not.
Advice appreciated....Mob$tarr

Sounds a bit serious, not the sort of thing I'd risk, it's not as-if you can tell your opponents to go easy. :-/

So, I went to the doctors found out I'd done some cartalidge damage to my knee so he advised me not to compete. So today i went to watch, however temptation got the best of me and i walked away with bronze and my knees feel fine!!

You nutter, but congrats. :o)
