Greetings. So sorry about your chest pain! My wife has had hard chest pains -- esp. under stress or when walking up inclines. She did a stress test - failed it - and the cardiologist gave her a nitroglycerine spray which, when used prior to walking, totally eliminated the symptoms! He was quite sure she had significant blockage of the coronary arteries. Yesterday (8 September), she had an angiogram which showed that her c. arteries were "totally clear". SO, whence the pain?
Diagnosis: "cardiac syndrome x" - a faux angina that has been much studied.
That MAY be your problem, as it is often debilitating.

Here's a bried description and some links:
What is it?
The term cardiac syndrome X was first used in 1973 to describe a condition that to this day remains a bit of a mystery.
Patients with the syndrome suffer the same chest pain as those with angina
For example, patients with the syndrome suffer the same chest pain as those with angina. In angina, this pain is often triggered by exercise and is caused by a narrowing of the arteries allowing insufficient blood to the heart. In cardiac syndrome X, the pain may also be triggered by exercise. When a treadmill or stress ECG test is performed to investigate the cause of the pain, the result is positive. However, when an angiogram - an x-ray dye test of the coronary arteries - is performed, no narrowing or hardening is found.
There's still no agreed definition of cardiac syndrome X. However, it's generally thought that to make a diagnosis the following criteria need to be fulfilled:
angina chest pain
positive stress test
completely normal coronary angiogram

which virtually rules our microvascular dysfunction which is commonly assumed
to be the cause.
