Hey i would just like to know I went for a cr scan coz I have been suffering from headaches above my left eye and my brain one came back clear and they say my sinuses are clear aswell except that I have basal polyploidal mucosal thickening in the left Antrum what does that mean ? I ha e also experienced pain above left eye with no headache when I move my lips of blow air into my mouth it only last while I do that and goes away then ?
