To answer your question I had no congestion. Prior to seeing my PCP I went to a walk in clinic to see if they could explain the thumping. He jumped right in to the congestion diagnosed my with eustacian tube disfunction. He told me to take MucinexD 2x a day and he believed the thumping would disapear in about a few days. I took it religiously for 2x weeks with no results. Then when I saw my PCP he thought the MucinexD was a waste of time. He referred me to an ENT and recommended using Flonase prior to seening the ENT. I used Flonase religiously for a 2x week period prior to seeing the Audiologist and ENT. By the time I saw the Audiologist I could still hear the thumping but it had quieted way down. The Audiologist asked me if I had tried using Flonase. So they were the second doctor who mentioned Flonase to me. A week later I saw the ENT and it seemed to have disapeared completely. I have no idea of the Flonase helped or not. I thought I would mention it because I had 2x different doctors mention it--good luck to all of you. I hope your thumping goes away the same as mine did!
