hi Orcoz

The way you are describing pain, I'd be wondering about the doctor. but go and get a professional bike fit. Don't wait. You COULD damage your knee and never be able to ride without pain.
Make sure the person who fits you knows what he's doing. I recommend Erik Moen, he's a Pt person and specializes in bike fit. If you have a cool doctor they can send you a referral to see Erik. GOod luck
and don't over train for STP it's not THAT hard.
