My nose is almost always really stopped up and it’s

Patient: My nose is almost always really stopped up and it’s very annoying! My left will be stopped up for a few hrs and then it’ll go to my right nostril! I keep my nose pretty clean and free of nasty boogers and snot. I do blow my nose and snot does come out but when I blow it again there’s nothing but air! Very annoying and hard for me to sleep at night. Do you know why this may be and why does it happen so often ?

Symptoms: Stopped up nose
