I have had pain in my right knee for awhile now, it starts above my knee and kinda feels like a rubber band is pulled super tight across my knee cap, it hurts when I stand from a sitting position and it hurts when I go to sit from a standing position. After I move it back and forth a few times, like squat down and up or some leg extensions, it is ok until I am in the same position for awhile then it hurts again! When I do legs it kills me, I have to squat and stretch it out and walk around and move it after every set for like 5 mins or more, it make my leg day super long and painful. It hurts everyday and just getting in and out of the car is painful. I went to the doctors and talked to him about it and had him take xrays of it to see if there was a bone spur or anything that would cause it and he said the xrays came back fine, he checked me for arthritis and there is none. I did some research and found that I have every symptom of quadriceps tendonitis. The quad muscle actually turns into a tendon right above the knee cap and then attaches to the knee. I talked to my doctor about it a couple of days ago and he set me up an appointment with a specialist to find out what it is and what to do about it. He said I may have to get an MRI but he will let the specialist do his thing and decide that.
From what you said about it hurting above the knee and so close to the knee it sounds like the quad tendon to me. So I would suggest doing some research on knee injury problems and their symptoms and see if you can at least determine what the problem may be and if you need to see a doctor.
Thanks
