I have chronic sinus, is there something that can be done?

I have chronic sinus from april this year. I have been on 2 or 3 rounds of cortisone to help. I have tried every possible alternative therapy. I have removed wheat, gluten dairy and sugar from my diet…. but i am still battling like crazy sinus since sep.

Looked inside my nose tonight. It was extremely red with a small yellow type growth on it. Maby a polyp ??

What are the solutions here…..i cant carry on living with this sinus
