hi

i would like to briefly submit my ear problem. On Oct. 26 i have taken a flight which has lasted less than two hours. Right at the taking off i have experienced a sensation of aural fullness, reduced ability to hear and a slight pain especially in my left ear (when i got on the plane i had a mild cold)
Today, ten days after my flight, my condition is getting better. Nonetheless, i am still experiencing similar problems in my left ear. In particular I have a permanent sensation of aural fullness and i can hear my own voice in a distorted way (autophony can vary during the day). Both these sensations disappear when I lie down.
Given the symptoms my ENT doctor has diagnosed a patulous eustachian tube (but did not do any exams). Due to the presence of catarrh in my middle ear he has also suggested to take a cortison based medicinal for about one week.
I had already experienced a distorted hearing of my voice in the past, the first time many years ago, but it has always lasted a few seconds and has happened very seldom.
I am supposed to fly to the United States (from Italy) within four days and i wonder if my recovery could be impaired by such a long flight. Has anyone experienced any similar situation?
any advice will be very appreciated
