I am in fairly good shape and exercise or walk five days a week, but after playing Pickle ball, about three weeks ago, I now have pain in my knee in the back and the front of my knee. It was the first time I ever played Pickle ball and the fast pace was hard on my knees. I have iced it and take Advil and it seems to get better, but the next day it hurts again. I am able to walk and even go to the gym and use the oliptical machine. It doesn t hurt then, but after a while it hurts again. Do you think it will get better on it s own or could I have torn something in my knee.
