My knee hurts when I kick a soccer ball. Possible serious injury?
I've been playing soccer for approximately 11 years, and suddenly yesterday, as I was playing soccer, my knee would hurt whenever i kicked the ball. It felt sort of like a popping/dislocating feeling. I can walk and do other things fine, but when i kick the ball it hurts badly. The pain feels like its coming from under the kneecap. Any suggestions/help would be greatly appreciated.
