[|Human|] Hi my son fell and hit is head about 30 minutes ago. He has a big knot on his brow bone. Its a little purple not bad though. Its the hard knot that worries me.and he still has the imprint of the counter top.. he is acting normal but all of a sudden he is saying he is cold. Is this normal? Or do u think he needs medical attention?
[|AI|]  Hello, Thank you for contacting me at "Ask a Doctor". I will try to answer your question to the best of my ability. It sounds as though he has a local contusion to the area. Apply some ice, and give him some ibuprofen or Tylenol.  If he has any signs of concussion such as dizziness, nausea, vomiting, Chat Doctor. , then you need to take him to the emergency room. I hope this information is useful for you. Please do not hesitate to message us back if you have any further questions. Best wishes, A
