Hello and thanks for the query
Bleeding in sinus infection
is not a good sign and you must consult your treating doctor as soon as possible. Every efforts should be made to control the bleeding from nose. Bleeding occur due to injury
or peeling of the tissue and that may increase the area of infection.
It is good that the congestion is reducing but bleeding must be stopped first if it is worse. In my personal opinion you must consult your treating doctor for further management.
