I have dryness inside my ear way down deep, seems to be a lot of fluid following sinus pressure. For two day I feel like my ear is going to bust from so much pressure. A lot of pain. This is the 3rd time this has happened in a few months. The 1st 2 times Dr diagnosed with ear infection, but this always happens after the dry patches inside my ear seems to swell, itch, and burn. Can it be something besides an ear infection?
