hoping that I can ride through the pain
I don't think this is a good idea. Knee pain from incorrect
setup won't get better, it will only cause permanent
damage to your knee.
Saddle adjustment is a fine tuning excersize, 1mm here
1 mm there.
Read this thread specifically the Plumb bob technique
(thanks Velocipedio and Pat5319) for saddle adjustment
Plumb bob
the pain is only on my left knee - right is fine
This may be a result of your left leg and right leg not being
the same size. I'd suggest find a position that is comfortable
for both, although this might be a compromise position.
Best bet, is go get professionally fitted.
