I have had the same problem. Mine has been just liquids also. I've had x rays, barium swallows, etc, and nothing. My doctor was convinced it was some kind of anxiety disorder, but the trial of medication did not relieve the problem. Now it comes and goes. And I live with it. It's very scary when you are unable to swallow your own spit. I am curious if they have figured out your problem.
I'm not sure what kind of scope. So far it's just been an ENT. Seems they don't take my symptoms seriously.
Hmmmm....difficult to say what this is if you have had a normal barium swallow and a normal "scope."
What kind of scope did you have?
What kinds of physicians have you consulted already about this?
Yes, I've been scoped and had a barium swallow and the docs say there is nothing wrong that they can see.
Have you had any endoscopies (scopes) of your esophagus at all?
Have you consulted your physician about this?
Definitely don't return to anyone who is not taking you seriously.
I would recommend an Upper GI Endoscopy and of course an assessment by a GI Specialist.
