i have the exact same issue as you. I hope you get help. For years I got ridiculed by doctors who thought my problem was anxiety/depression related. Now I throw up all depression pills. only anxiety pills help me a bit. if that is cancer you want to find out fast. soon it might affect you mentally. i already know i have it because i'm not responding to even any antibiotics or anything else, but i'm waiting to do tests. you want to ask the doctor to do an ultrasound and UGI test. That is what i will be getting done in two days and i can't wait because i need to get this condition under as much control as possible. i've been getting spasms as well in my face, so i know whatever i have, it's probably gotten pretty advanced. not my fault either.
good luck.
