I am going thru this now, I've never heard of this before, I felt so alone, I started a week ago and I am very concerned now, I feel a little pain in my esophagus, as if all the food was trapped, not going down, and the food comes to my mouth, sometimes acidic, sometimes not... it's annoying.
I read what you said the doctor advice about the vitamins, I've been taking a lot of D3 and B-12, I wonder if that is causing this...please let me know if you feel better/found a cure.
Thank you for taking the time to post your problem!
