Hi guys thanks for the advice. It may well be patella tendonits but I don't feel it in my patella its more in the bone. I stretch pretty much everyday anyway so im fairly flexible but will add the stretches you suggested.

The initial problem presented after lots of squats with heavy weight and poor form, I was on my toes too much which would make sense if it was tendonitis. I guess there is not much that can be done for that. I did initially try resting the injury for a couple of months but I think because we walk so much anyway its hard.
