Hi I Have A Question About My 7 Year Old
Compress nose for 10 minutes.
Detailed Answer:
Hello dear, welcome to Ask a doctor service.
I read your query and here is my advice.
Nosebleeds are common in children while suffering from viral infection. The throwing up caused an increased pressure and made the blood to go to tear duct.
You should make her lean forward and compress and punch nostrils in the nose bone level making her breathing through mouth. Keep it for ten minutes and then remove hand and see if it is still bleeding . If the bleeding persists repeat compression for another 15 minutes. Most probably it will stop but if not then you can go to ER.
You can give her low dosage of vitamin C to help protect the blood vessels.
Hope I have answered the question.
Let me know if I can assist you further.
