Thanks for your query.
Since your child is having fever
for last few days and he is not well also ,i advise you to get him evaluated by pediatrician
for proper management.
He is having recurrent nose bleeds this also needs to be evaluated.
Cause could be infection/nose picking/local trauma.
I suggest you apply cold
compresses over nose and pinch nose for about 4 to 5 minutes in case of bleeding.
Give plenty of fluids.
Wishing your child good health.
