Symptoms:
Is a very wet layer that helps protect the inside of your nose and sinuses and humidifies the air you breathe.

A polyp is a round growth (like a small cyst) that can block nasal passages.
Preliminary plan:
A sensation that your nose is blocked
Runny nose
Postnasal drip, which is when excess mucus runs down the back of your throat
