Re: Unstable Angina
I'm sure someone more knowledgable will correct me if I'm wrong, but my understanding is that unstable angina is a result of SEVERE heart disease; I seriously doubt you would have "passed" the tests you have had if you had unstable angina.
Pain in your back on the right side might indicate a gall bladder problem. The pain in your chest is most likely anxiety related, or just a common sensation that we all have from time to time, or might also be gall bladder related.
I've had stable angina (for 2 weeks before a 99% blockage in my LAD was diagnosed and a stent placed) and all I can say about classic angina symptoms is you'll probably know it if it ever happens to you: it's like no other pain or chest sensation I ever had before or since and is kinda like an elephant sitting on your chest and squeezing your heart.
I do understand the issues with anxiety....now I'm much more sensitive to any aches and pains, especially in my chest area, but the doctors think I'm fine (and I suspect they're right because even though I've had some chest discomfort that has freaked me out, it has not been the same as the angina).
