My 5 year old was running or way when a 10 year old came running around the corner and they collided. She feel backwards hitting her the side walk. She cried for a few minutes and had a good size knot on the back of her head. She has been acting ok otherwise although is tired but had been playing outside all day. Does she need to be seen by the e.r. or doctor?
Hi... Thank you for consulting in Chat Doctor. I understand your concern. First be reassured that your kid is normal. I will suggest you danger signs of head injury -1. Vomiting continuously2. Seizures3. Watery of bloody discharge from ears and nose4. Unconsciousness5. Altered sensorial or behavior. If none of them are present, I don't think you should worry about his trivial head injury. For pain, you can give oral Paracetamol in the dose of 15 mg/kg/dose(max ceiling dose 500 mg) every 4-6th hourly.  Hope my answer was helpful for you.  I am happy to help any time. Further clarifications and consultations on Chat Doctor are welcome. If you do not have any clarifications, you can close the discussion and rate the answer. Wish your kid good health.
