I suffer from constantly clogged (stuffed) nose, usually alternating left and right. Pain sometimes behind my eyes (left or right alternating) when i look to the egde of my field of view. Dry eyes (sometimes itchy). Headache, localized to my right side above my eye almost above my temple. Constantly clearing my throat. This started five years ago as a stuffy nose after a cold and has never subsided. I am wondering if anyone knows (or has suffered) the same symptoms and is this sinusitis? Please help before I go crazier :) thx...
