When I tap or press lightly on my face, I get a light "rushing" sound in my ears like the wind is blowing lightly. I know, I know--a little nutsooo! But actually, I get that same rushing sound in my ears when I press lightly on most any part of my body, arms, legs, etc. I've just always chalked it up to the nerves in my body responding in some weird way because fibro is a nerve-pain-brain not working properly, kind of disease.
I haven't any of the fullness feeling you write about. I do have the something in the eye feeling alot and don't particularly have dry eyes.
Hope you find some answers soon.
