You've got chondromalacia patallae, read about it here: http://en.wikipedia.org/wiki/Chondromalacia_patellae
I've had it quite badly from sitting too far back when skiing. It will go away eventually, but make sure your saddle is set at the right height, i.e. not too low.
Now cancel the appointment and send me the consultancy fee in beer tokens.
+1, Patellofemoral pain. I have the same thing, due to muscles in upper legs not working equally. I get it in my left leg and can feel the inflammation and fluid squirting around kneecap. Physio noticed I overpronate and gave me a small rugby ball to squeeze between legs to work on my inner muscles. I find walking helps and cycling make it worse unless I really concentrate on using inner leg muscles when pedalling.
Again ultrasound and x-rays with me showed no cartlidge damage but it hurts on a regular basis.
