Please advise: My 12 year old son, fell a few weeks ago. He was playing basketball on our concrete driveway and landed directly on his knee (in a kneeling position). His knee began to swell and we immediately began RICE. I also gave him ibuprofen for the pain. Now, anytime he bends his knee and his jeans touch it, he complains of pain and a burning sensation. He cannot put direct weight on his knee even on a soft surface without complianing of pain and a burning (that he describes as a hat spreading across his knee). This injury has not slowed down his running and there is no physical evidence of injury. He has carried on his daily activities, just has a complaint about twice a week with the above symptoms. Now what?
