Thank you for your query,
Because of weak blood capillary plexus, forced sneezing
leads to nasal bleeding
Gently press and close the nostril which is bleeding and hold it for some time so the pressure stops the bleeding and whenever nasal bleed is there you can do it but one nostril at a time only.
every 6 th hourly for fever in prescribed dosage and consult your Pediatrician
to evaluate the cause of fever and to assess the nasal bleeding.
Hope i have answered your query.
