I too am suffering from Sinus problems over the years. I started using Biotin, B6, B12 All VEG, copper 100mcg, Iron(if Hypothyroid). Also, try some raw potato because there could be a problem with superoxides like H2O2 (Hydrogen-Peroxid) and stay away from refined sugur, sodas, caffane but use herb teas. It will take a few months but they will bring your sinus under control. You could also be exposed to some pollution in NY. If nothing else you may have to relocate. All the Best
