Hi thanks for your question.
,blocked nose are common in asthamatics and get precipatated by allergies.
Epistaxsis is common in rhinitis
that is infection of nose.
If bleeding is less there is nothing to worry.You need nasal decongestant ,antihistiminics and addationally you may also need antibiotics.
Nasal trauma due to nose pricking is common precipatating factor.Avoid that.
In case of sever bleeding please consult ER
Hope this answers your question.
