My mother also has severe chest pain. She went thru alot of tests including cath. of her heart. They said it wasn't her heart. She has really bad reflux and that is what causes it. If she doesn't eat the right things she has chest pains. Tomatoes and cake are the worst.
Can you tell a difference in what you eat?
For some reason the heart medication worked on the pain. She has been trying a lot of different acid reflux medication by prescription, trying to find one that does not bother her.
It is really hard to believe but this pain does feel like a heart attack.
