My opinion is that the reason you will get so many diagnoses is because they don't really know whats wrong. It's so easy to just throw a name of a disease or dysfunction at you rather then really looking at you.
The first time I went, the ENT checked my throat, nose, and ears then after 5 minutes of talking to him he prescribed me ativan, told me the pressure in my ears is normal, and learn to live with it.
My suggestion to you. Your symptoms are normal, so take an ativan and relax!

Just know your not the only one....
