Minor recurring knee pain? ?

It's the same for me! Apart from I'm 13 not 14. Anyway, I had fluid in my knee and injured it further while skiing. I had physio therapy for it and recently it's got worse again, but probably because I haven't done any of my excercises :L oh well, just go and get it checked out, especially if you are doing netball next season as it has a lot of strain on the knee from twisting and things.
