How comes if im seated, and my leg is kept bent for too long i get a dull ache just above my knee cap, not over it but above. Then because of this ache i go to straighten my leg and there is stifness followed by a very severe pain above the kneecap where the ache was

Sounds like a possible case of movie-goers knee! This occurs when the knee is bent for long periods.
Pain is termed anterior knee pain and can be anywhere around the front of the knee. This can be caused by a few conditions, such as patellofemoral pain syndrome or arthritis (depending on your age!)
