Both Ada & I mentioned esophageal spasms.
They truly feel EXACTLYlike a heart attack. Right over the sternum and can radiate to the jaw or arm.

Did you check info on Variant angina?

Please, please get a copy of those medical records and if you can let us know
if there were any EKG changes. AND if so, what are those changes?

This may not disappear and how can you treat it without a diagnosis?

I have exactly what Ada spoke of - Thoracic Outlet and fibro too.
Both can cause chest pains with NO EKG changes. I had the elevated T-wave on my thallium stress test.

Please don't ignore this. I've seen people turned away from ER's because of no EKG changes and they went home & had heart attacks.
We've given you some things to think about & read up on.
Doctors are human like us and miss things.
Keep doing trying relaxation exercises even tho they did not help me, they help some.

I will say prayers for you and that God will work thru the doctors to find a diagnosis,
Have they examined the GI route? Endoscopy?

What was the outcome of the angio?
It is just that Ada & I both know how much this hurts. I had to sit so still and not move - I would breathe so shallow because I thot I was having a heart attack.

Ada's right, chostochondritis is a common diagnosis for this (not dangerous)and anti inflammatories help, however can cause an inflammed stomach lining - therefore add more to the mystery.
We care for you & don't want anything to happen to you.
Thanks all you people for your prayers for Sandra.
Hope
