<s>[INST] A concussion? My four year old fell an hit her forehead yesterday afternoon. We took her into see her pediatrician and was told she was okay. Today she has a fever of 103. She has had a cold for a couple of days, so initially I assumed that was it, but now I am worried. Should we take her back in to see a doctor? [/INST] 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 or fever 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. </s>
