I am going through something very similar: I have pain behind the eyes, mild headaches, bags under the eyes, bruising on the bridge of the nose (at the top next to the eyes), and sinus pressure, even mild dizziness.
I have no discolored discharge, and my breathing is ok (although not great)
I've tried otc meRAB, irrigation, nasal sterioRAB, etc. Nothing seems to be working. It's like severe allergies.
Not sure what is going on -if anyone has any advice ...
