Have you heard of this related to inhaler dust? And what do you do about it?
I developed irritation inside my left ear, which has haunted me for a few months. My primary doctor calls it ETD - eustachian tube dysfunction. Docter and ENT are guessing what to do about it.
Ruling other things out and given the timeline, it seems to be the inhaler dry dust (no steroid, just one drug LAMA) that coats the upper throat and irritates the eustachian tube.
I read, "Rapid inhalation of fine particles (dust) from an inhaler can deposit medication or filler powder on the surface of the Eustachian tube orifice, which can potentially cause local irritation.
What seems to be helping a bit (cross my fingers) is the following. Rinsing and gargling clears the upper throat residue but does not reach the tubes. I then began afterwards, swallowing a glass of water, which briefly opens the tubes, that can wash away remaining material from the nasopharynx area.
