Thank you Danni! That does help my search a great deal. It seems very similar to what I have in every way except that it seems as though the 'opening' and 'closing', particularly the closing is not easy to control. In my case it is. I can close my ears easily, by reducing pressure in my nasal cavity (sucking through a closed nose), whereas it seems that most people with patulous eustachian tube have to resort to methods such as putting their heads between their legs or lying down.
Alas! It seems as though treatment is few and unreliable at best
I have noticed that over the last couple weeks I've had a constant sore throat which seems to have coincided with exaggerated p e tube symptoms. Could there be some relation?
