I don't know if this will help or not, but this is what happened to me. My eyes would itch, burn and be dry to the point of hurting. I also had terrible sinusitis. I did a 3 month Candida diet and took supplements to get rid of it. My eye problems and allergies went away. Candida is a naturally occuring bacteria in our bodies but when it becomes overgrown, can cause various "mysterious" symptoms that seem to have no cause. Dr. Crook's Candida Handbook is a good place to start.
