wheni sit down for to long i get pain, kind of like an ache behind my knee which works its way up my leg the longer i sit down. ive had this on and off for ages, about 2-3 years and in exams its horrible. i have to fidget all the time to stop it hurting so much. i was just wondering what this is?

I would bet money it has nothing to do with your knee, and is all about your spine or hip. (your lower back in particular)
Try to sit with a decent posture, with your back against the back rest to reduce any strain on your lower back. THat'll help more than anything.
