reflux up in the nasopharynx

An ENT doctor did a scope in my nose and told me I have stomach acid bubbling up into my nasopharynx by the eustachian tube opening which is causing ear pressure that I am experiencing.  A different ENT and 2 pharmacists that I have talked to both seem skeptical about this diagnosis.  Is this common, and should I be concerned that I have stomach acid making it all the way up into my nasal area?

I also should mention that I have a bit of lightheadedness or vertigo from time to time, a feeling of constricted throat and shortness of breath once in a while, and I think some or all of these symptoms are aggravated or completely brought on by an anxiety that I develop over my health.

The ENT that did this scope and saw the stomach acid by my eustachian tube also had me undergo a soft tissue MRI of the head and neck (which his nurse called and said showed no signs of cancer), but I'm still worried about whether or not reflux of this type could be (or already has been) damaging to my stomach or esophagus.
