So sorry you've had that pain, @SuzyS .... any chest pain is extremely frightening & I hope they ran tests to make sure it wasn't anything else. I had pericarditis once & thought I was having a heart attack .... I think rest & a course of antibiotics fixed it .... and GERD is never pleasant either. Do you have the head of your bed raised a little? I have mine on a brick (under both legs) and it prevents the liquid from rising in the oesphagus during the night (when it is usually more active.)
I hope the change in meds helps you. Take care
