"if it is anterior (front of the knee pain) at the bottom and just below your knee cap, then your mechanism of injury suggests fat pad impingement or irritation, as in:
" if a swimmer presented reporting pain following ... a forceful extension of the knee, the practitioner should suspect an irritated fat pad"
anyway- ice, rest and anti-inflammatories (with food) are always good for knee pain."
Dern it! It's just my "fat pad"!
I have avoided irritating it, used cold compresses, and have been taking a NSAID to reduce the swelling.
Now I seem to have a hankering for some tuna.... and a bowl of cream... =)
Thanks Claudia, for the unofficial / anecdotal / but very helpful consult.
