It took me 2 years to find out what was wrong and I had many of the same syptoms as you. Ask your Dr to examine/test function of your cricopharyngeal muscle. If you have cricopharyngeal akalasia , you may benefit from a med called: Clonazepam. Cricopharngeal akalasia presses on the vagal nerve - causing almost all of my symptoms - many of which are the same as yours. Good luck!
