Sinus infection and nasal polyps. Exams.

Hello sir/madam,     My name is hardik and i am suffering from sinus infection and nasal polyps since around 5 years. I had passed through one surgery in june 2016 by ENT doctor.     After three mounth of operation the problem begin to start with same way which was it before.     Problem Statement:-     Right now my nose is completely block at sometimes but not both nose at a time. But during couple of days it is blocked together.     Its fill like some stuff is stuck inside the nasal strip and it transfer to other nose. It is very difficult to take breath at night as well as in day.     I AM USING XYLOFLO NASAL STEROIDS FOR TEMPORARY RELIEF SINCE 2 YEAR. But not Daily.. When it's needed most. And i also use of neti pot with saltnezz tab.     I have CT scan which is not older than 1year. I can attach it's photo if needed.     I really appreciate the expert advice on that.. It's very irritating and also difficult to focus on preparation of exams.
