Hello madam! I read our query and i see two troubles one is nose bleed and other is dizziness both after traumatic episode to chin. Let me assure you if this bleeding nose is not some recurrent thing or some bleeding disorder with previous multiple recurrent episodes then you need not to worry about anything. All you need to do is to avoid hot and spicy foods for her and let her drink plenty of fluids.avoid strenuous activities, hot showers, and digital trauma. You should use nasal saline spray liberally and should employ digital pressure and ice packs as needed for minor recurrences. Hope they will suffice. Now the dizziness. It could be nothing. But i would recommend to see a paediatrician for ruling out any intra cranial injury during the fall which may lead to dizziness all this to be on the safer road. other wise a simple flu can give dizzines too. Just let her rest and treat the symptoms with some anti emetics like metoclopromides and hope for the best. Your daughter dhould be proud to have a mom like you. I wish you very good luck and take some very good care of your daughter and yourself Cheers Dr Khan
