I too suffered with the pressure in the ears and been through numerous tests and many doctors. Finally after going to a neurologist the diagnosis was Meniere's Disease which is horrible, ringing of the ears, uncontrollable vomiting, blacking out and hearing loss, there is no cure for this, but they try to keep it under control with meds. I also have TMJ which they said is not a result of this. All I know is that I have this and I wish I didn't.
