I can recommend a good one, as seen by the Streat as well. He couldn't do anything for me, unfortunately. The operation only works if you have structural issues (they clip off a tiny piece from your nose bones so your sinus openings are bigger, but it grows back after a few years). My issue is that my mucosa are allergic to everything and swell up at the slightest provocation. It's a lifetime of cortisone nasal spray for me :(. I did get a cool CAT scan of my head, in which I could see the tiny sinus that's near the base of the brain. Apparently my ENT assists in brain tumour operations where the only way to get to the tumour is through the nose.
