Ugh, that sounds horrible. And I thought I had it bad. I haven't pursued any other diagnostics since this all started. It sounds like I might have 1 of your dysfunctions...where food gets stuck on the way down at the esophagus and yes...it feels like a heart attack. Super painful. I suspect that, after a plethora of tests, they either won't find anything or, like you, won't be able to do anything about it. Do you take any meds for any of this? Thank you for reaching out
