Hi There
I have been facing this issue for over 2 years now
Did Upper GI , endoscopy, colonoacopy, CT with Barrium
Tried every medication you can think of
However I would say Motegrity may help
So, I'm in a wheelchair and every Doctor told me the same thing. It's a Posture issue.
Some food cause irritation in which case gas radiates to the back, abdomen, left breast, and then xyphoid process. Sometimes it feels like I will have a heart attack.
This is what helped me a lot. When you eat or while you wrap this tightly on your chest not waist. Cover both nipples and arm pits and make sure its snug .
For the long term get a posture corrector. It really helps if you use it everyday as per instructions .
Also, warm water packs help
Did you have your Gall Bladder removed?
Did you fall or injure your upper body in last 5 years?
