The conversation between human and AI assistant.
[|Human|] Yesterday, I hit the top of my head on the edge of an open wooden cabinet door.  I automatically had a headache and a small knot.  I felt a little nauseated but did not vomit. I felt better after taking some tylenol.  Today I my head is extremely sore and I have a headache.  Im really worried.  I did make a doctors appointment for today.
[|AI|]  Hello dear, The lump formation after fall 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 taking analgesics like Tylenol, ice compression & adequate rest. If it still persists or there are any other associated symptoms like fever, vomiting, visual disturbance, loss of consciousness, convulsions, etc...then it will be better to consult your Doctor. Under such circumstances, a CT scan of brain will be needed to rule out any pathological cause for symptoms. Wishing you a good health. Take care.
