[|Human|] Hi, may I answer your health queries right now ? Please type your query My 8 year old was hit in the head with a baseball bat. It immediately had a knot, no bleeding. He seemed fine and has been since. Tonight, I noticed a bald spot where he hit his head. Should I be concerned?
[|AI|]  Hello dear, The knot formation in head after injury is due to accumulation of fluid & blood, and it is called Hematoma. The blood cells accumulated are eventually broken down and absorbed in the body. But this is a slow process & takes times to disappear completely. Till that time, symptomatic relief is obtained by analgesics preparations, ice compression & adequate rest. If it still persists or there are any other associated symptoms like fever, vomiting, loss of consciousness, convulsions, etc...then it will be better to consult his Pediatrician. Under such circumstances, a proper clinical+ radiological evaluation will be needed to rule out any pathological cause for symptoms. Till then, maintain adequate HY Chat Doctor. There is no need to worry, he will be fine. Wishing your son a good health. Take care.
