Ok medics
Sitting at work this morning (very stressed) I experienced some severe chest pains that came on very suddenly. No other heart attack" symptoms, just nasty squeezing pain in centre of chest, behind sternum.
Now bearing in mind that my heart valves, blood vessels etc were declared lovely a couple of years ago, and I have a minor electrical prob with heart,
WHAT IS IT?
Apart from heart, what could it be?
