Conversation: The conversation between human and AI assistant.
[|Human|] 7 weeks ago, I collapsed and fell backwards hitting the back of my head on a concrete driveway. I did not lose conscience however, I had a severe headache for a week following the fall and continue to have dizziness if I turned my head or rollover in bed. Also I find I get angry quickly. Experience occasion balance issues.The ER doctor did a cat scan the night of the fall. There were no signs of bleeding in the brain.
[|AI|]  Hi, I am Chat Doctor.  I have read your question and understand your concerns. Let me try to help you Let me discuss this from two points (I)Dizziness and Balance Issues can be due to Reduced Blood Flow in Posterior Circulation of the Brain (II) One of the less frequent complications of fall is Chronic Sub Rural Hematoma. This can also present with Headache So I would advise you to consult a Neurosurgeon and have a full evaluation to rule out posterior circulation low perfusion / Chronic Sub Rural Hematoma Hope you found the answer helpful. Anger can be an unrelated issue and hence I have not gone into details about it If you need any clarification / have doubts / have additional questions / have follow-up questions, then please do not hesitate in asking again. I will be happy to answer your questions. Let me know if I can assist you further. Take care.
