Who would have the most knowledge on nasal mucus, ent, ent professor, or a bioligist, and also is nasal mucus/contents of the mucus be dangerous in anyway,thank you.

As far as I know nasal mucus is not dangerous there are a lot of nose pickers out there who seem to thrive on their habit! As for any problem that you might have with nasal discharge if your now doctor could not help you I am suer that you would be referred to an ENT surgeon. Nasal dish cage that is unexplained does need to be looked at.
