[|Human|] My son fell on his knee when roller skating a couple weeks ago. there is still a bump on the lateral upper side of his knee. He says it has a burning feeling when he rolls onto it in bed and when the bump is pressed. He says it feels like a bruise at times, but there is no coloration of a bruise. Could it be a torn tendon? He says it doesn t hurt when he walks or straightens his leg. Should I get xrays or give it time?
[|AI|]  Hello, Your son is most probably having post-traumatic synovitis at knee. This is just like mild inflammation of soft tissues. There may be mild injury to inner structure of knee. In response to this knee secretes some fluid to heal those structures. At present, I will advise you to give him rest and avoid sports activities. I used to give mild analgesic anti-inflammatory in such cases. Hope I have answered your question. Let me know if I can assist you further.
