Secondly, no doctor has told me I couldn't do anything physical. It's never happened while cycling *knocks on wood* and I'm not sure it would because you never fully extend your leg while pedaling. And pedaling is a consistent, fluid motion - not sudden or jerky or apt to apply weird pressure randomly. I don't wear braces, it most likely wouldn't help anyway.
So your patella is in its normal track during your normal activities. When it goes wrong it totally goes wrong. Mine is not like that. I think it is pushed outside by a small margin and it always gets rubbed to the femur during its activity which causes inflammation afterwards. I can't describe this phase very well. It is not like a headache or something. There is no sharp pain but it is kind of directly affecting your brain chemistry and puts you into a depressive mood. You don't have it so you can't feel it.
