[|Human|] After getting hit in the head by a crow bar on a job site, I began to experience the symptoms of a concussion. It is now day three and I feel terrible. There is a horrible black eye and a warmth on the side of my head that was hit. What could the warmth be caused by and is internal bleeding an option?
[|AI|]  Hello! I read your question and understand your concern. Your symptoms are common after a head concussion. These symptoms are caused by a temporary brain dysfunction due to the head trauma, and the temporary loss of the brain ability to auto regulate its function. The warmth on the side of your head may be related to the edema of the muscles and the soft tissues of this region. The brain does not hurt. I would recommend some painkillers for some days and a lot of rest. You should avoid straining physical activity for some days. If the situation gets worse, instead of improving, and you may feel confuse or numbness on your limbs or gait problems, I would recommend going to the emergency room and have a brain CT scan to exclude a possible intracranial hemorrhage. Hope to have been of help! Best wishes!
