Doctor : Hi
Doctor : How can i help you?
User : Why does Sinus ear Pressure cause temporary tinnitus ?
Doctor : pressure difference across the tympani membrane causes abnormal stimulation of the hair cells in the inner ear causing tinnitus
User : Oh . I Went to my ent specialist because i have ear pressure. and He said I have sinus ear pressure. And now i have tinnitus. HE prescribed Fluticasonenasal spray to use for a month. When will it go away?
Doctor : once the inflammation reduces by the use of the nasal spray the pressure change also gets corrected and tinnitus also disappears
No idea how legit it is... But the reactive T here seems so connected with the pressure feeling. I hope it goes away.
I do believe that the reactive T and the pressure feeling is connected indeed. When my T goes away, so does the fullness. When it does, it kinda feels like someone slapping my ears. However, for me I do not believe its caused by ETD or anything regarding pressure within the middle ear. I believe in my case its caused by muscles. Primarily
tension to auricularis superior, auricularis anterior and the sternocleidomastoid muscle.
I do find it very interesting though, that it seems like you got this reactive T and fullness from using a nasal spray?
Could it be that you were kind of monitoring your T quite hard for a while when using that spray? Just curious
