My knee started to hurt one day when i was running to the point where i had to stop running. This was about 2 1/2 years ago. I dont run now as a result (which I hate) but I am reluctant to see a doctor because a bad knee diagnosis could hurt my career. I can do biking or an eliptical machine without pain however. I also feel pain if i try to lock out my knee hard. I also noticed that if I push my right kneecap out to the outside (right), it glides much smoother. I'm assuming I have some sort of tracking problem but I'm not sure. Does this sound like a tracking problem and if so, what are the best exercises to pull my kneecap glide to the outside?
