Whats wrong with my knee cap

Question: Whats wrong with my knee cap

The other day i was running and then it hit me, almost burning point in my knee. It hurts to run on it for more then a mile. But i can do all flexibility on it as i can. I can lung, squat, and do anything on my leg as i want. All the pain is in is when i run. My knee cap pops when i extent it pass the straight leg stretch, and also when i kick my knee cap pops.
Please if you could tell me what the problem is?
