Patellofemoral Pain Syndrome?

Last night I went to my regular Ipswich Jaffa running club track session. It was a 3 kilometer time trial. I was quite happy I managed to knock out 12 minute and twenty something second. But toward the end of that session my knee started to feel quite aggravated. Coupled with Achilles Tendonitis and a major lack of fitness.
 Anyway this morning I hit the google machine and managed to find some information about what is going on under my knees bone.
Turns out it is something called Patellofemoral Pain Syndrome. Soreness when sitting for long time. Can flare up with overexertion. I have added links to the articles which  I read.

I am still going to visit my doctor to check my self diagnosis is correct.
