Hi, My Son is 13 1/2 yrs of age and has been playing football since the age of 7 1/2 as well at other sports, athletics, tennis. He plays football at a very good level and is training at least three times a week.(He is currently trialing for an Academy team) On a football camp this week he has noticed that when he squats to pick items out of a low cupboard his knees start to creak. (This is the first time that he s noticed the problem). He is a very fit and healty boy of slight to medium build, and approximately 5 feet in height. Is this something that will go as he continues to grow, or is it something that he should seek medical help for? I would really appreciate your help, thanks
