<s>[INST] Hi, I hit my head last night when I was trying to get up from sitting on the floor.I hit my head right where my neck and skull meet so maybe the brain s tr em area. It didn t hurt after the initial pain but it has really been bothering me tonight. Slight head ache and seems kinda hot. Not to the touch but I feel it [/INST] Hi dear user of Chat Doctor! Thank you for your question! I read your query carefully and understood your concerns! It seems you have a contraction or little edema (inflammation of your muscles behind the neck and head.It's a response to the hit you had. If you have not any other symptoms but just that light pain and hot feeling I would recommend you to take anti-inflammatory Chat Doctor. If you have other symptoms like dizziness, vertigo, severe headache, vision problems, etc., you better go to the ER and see a neurologist. I hope you will get better soon! Best regards! </s>
