Don ... We have been out of town since Thursday and I just had a chance to get to S-Z ...
belated HAPPY BIRTHDAY, and considering Susan's outcome, I would say that ultimately it was ...
As I was reading your posts about all the cardio tests being good I was going to suggest she be checked for esophageal spasms ... I cannot count the number of times I have been rushed to the ER with the exact same symptoms of a heart attack - severe chest pain radiating up to the neck and jaw and to the shoulders, sweating, lightheaded, etc. only to find - fortunately - that it was esophageal spasms ... One 'problem' is that the nitro they give you in the ER to relieve the cardio symptoms also relieves the esophageal spasms so they have to do all the tests, but better safe than sorry ...
I have been through countless tests for reflux and the spasms ... My Gastroenterologist has me on a daily 60MG dose of 'Dexilant' ... the spasms do not occur as often but the severe pain and other symptoms are still the same ... at least I now feel I can tell that it is a spasm and not a heart problem ...
Get her to a good Gastroenterologist and ask about 'Dexilant' ...
Wishing you both good health and many more years ...
