I have noticed that after a bout of intensive excercise i can feel a bump on the top of my knee cap where it meets the quad - this bump hurts if i press down on it. Could this be an inflamed patellar tendon?, it only hurts when i put pressure on the bump, although the knee does feel stiff and gives me some clicking. A set of medium squats without proper warmup brought this on🙁. Any ideas/treatment advice would be appreciated.
