I have what I believe to be a sinus infection. I still have a bit of a cough, sore throat, sinus pressure in my nasal passages, my forehead, and my ears. Once in a while, when and after I cough, I hear ringing in my ears. I have also has pain in my ears simultaneously. Currently, I have lost hearing in one of my ears. I woke up this morning and couldn't hear a thing out of it. What should I do?
