I get sudden Tight unbearable pain near heart. This comes suddenly and will last for few minutes. This also accompanies with feeling like an passing electric shock around my heart. Its been one and half year I started facing this. Underwent coronary angiogram, ECG, chest X ray, DDIMER, trop T. All are normal. I am not diabetic and not hypertension patient. Lipids are under control. I work out regularly, atleast 5 days a week. I observed this pain getting increased when I do abdominal exercises when lying on back. Due to this i stopped workouts and started walking...kindly help explaining what is this pain all about, your help is very much appreciated. Thanks in advance...
