Antrochoanal nasal polyp. For the same?

I have been diagnosed with left antrochoanal nasal polyp in 2018. My ENT specialist tried everything but only option for me is to go for surgery. I do get frequent infections that have blood mixed discharge from my left nose. i breathe from right nose and mouth only. i am scared of surgery very much. i have heard dupixent(duplimab) a biological injection to treat polyp, i am unable to find any ENT doctor who can work with me on this, i know that injection is costly but money is not a problem. i just want to avoid surgery. i am very much scared or surgery and can't even give blood for blood test easily because i am scared of needle too. Is Dupixent helpful to treat antrochoanal nasal polyp or no? if yes then can it be done in India or i have to visit another country for the same?
