Heiferly is right in directing you to an ENT. They can check out the common problems that could lead to your symptoms which include such things as hiatal hernia, reflux, and reverse peristalsis. You may have a little pocket in your throat catching your food which then makes it easier to regurgitate. Since you have thyroid problems as well the ENT no doubt would do a thyroid ultrasound as well if it hasn't been done.
As she also suggested keep a close watch on when it happens and with what foods. Do liquids or solids cause the problem. Sometimes reflux can cause the laryngeal area to swell and this can cause pressure in the throat area. Thyroid problems can as well. Both will be noticed as pressure in the throat area and you can have problems when you lie down as well. A good ENT can be very helpful in isolating what is wrong.
When you go in they take your history of the problem and ask questions. Often they will then after a numbing spray do a gentle scope of the upper section of your throat. This tells them a lot so they can then order whatever tests are needed.
Good luck with this and let us know how things go! Marie
I would start with your thyroid surgeon since you already have a history of that. My next step if that gets you nowhere would be to consult an ENT (ear, nose, and throat specialist). They (or a speech-language pathologist) can do a modified barium swallowing study; there are different protocols for this and you want one where they study varying consistencies of liquid/food from thin liquids up to solids (and in between):

There are also other tests that an ENT might want depending on what is suspected to be the issue. There are ways that they can look for constrictions in the esophagus, or other problems that might be causing your symptoms. (Admittedly, I'm not sure what might be causing your symptoms, but hopefully you can get answers sooner rather than later.)
In the meantime, I would be keeping detailed records on when the symptoms arise, what precedes the symptoms, what (if anything) tends to help alleviate them, etc. Anything that might provide any clue to the docs as to what is going on, even if you can't see the relevance yourself. If this is causing frequent vomiting, I would make a call to your doctor (likely your GP) and ask for an anti-emetic that acts directly on the vomiting center in the brain (like zofran, aka. ondansetron). I can't say for sure, but my guess is that that's the class of drugs that would be most likely to stop the vomiting so that you're not losing fluids/weight and getting dehydrated and throwing your electrolytes out of whack, which we know is a no-no for dysautonomia.
Keep us updated. By the way, one of our members does have a swallowing disorder but your symptoms don't sound the same. I've also had issues with my esophagus and swallowing/regurgitation, but not like what you're describing either; off the top of my head I'd say reverse peristalsis is more common in dysautonomia than what you're describing, but then again, I'm not sure exactly what it is that is occurring in your case, so I could be completely wrong. :-/
Sorry I don't have better answers on this one. Hang in there! And demand a zofran or something at least so you can keep food down for the holidays!! :-p Hugs,
Heiferly.
