Along the same lines as SuPu's ( http://www.tetongravity.com/forums/s...ad.php?t=54759 ), except mine comes with occasional pain

Symptoms: clicking/popping and slight difficulty bearing weight in left knee when I climb stairs or a steep incline. Don't really notice it when simply walking.

Clicking feels like it starts at 12 o'clock position under kneecap, and then migrates slightly southward as knee extends.

Fairly acute pain when snowboarding (specifically, shooting pain when using knees/feet to initiate turns). Enough to make me call it a season at the end of April.

Aside from diagnosis (which are appreciated), what kind of doctor should I go see? Ortho, sports medicine, other?

Can anyone recommend names in the Seattle area?

Thanks.
