so my nose has been stuffed for like 2 weeks. i thought i had a sinus infection. i could not blow or breathe out of my right nostril! so this morning i went to the bathroom trying to blow as hard as i could and finally i blew out alot of yellow liquid. this thick mucus looking string followed along. but when i tried to pull it out it really hurt. i was able to get some out but theres still a piece hanging inside my nose and im scared to try and pull it out. anyone know what this could be?
