For years I suffered with horrible sinus infections and would go on different courses of antibiotics for months at a time. My youngest daughters boyfriend suggested using a neti pot, and I use it faithfully every morning and haven't had a sinus infection for over 2 years. I am so mad the Dr.s didn't suggest it. Neti pots are like little tea pots that you use warm water and a tiny bit of salt and flush your sinus cavity, it sounds crazy, but it works. You can google it to check it out more. Walmart sells them for about $14.
