[|AI|]  Hello! Thank you for asking on Chat Doctor! I understand your concern, and could explain that all your clinical scenario seems compatible with an anxiety exacerbation (the way it starts, nonspecific and scattered symptoms, to end with totally non-specific piercing pain in your heart area). This doesn't seem to be heart related. So, do not panic! Just relax! I would recommend performing a routine medical check up by your doctor (internist or GP) for a careful physical exam, a resting ECG, chest X-ray study, and some additional lab tests (complete blood count, PCR, fasting glucose, liver and renal function tests, etc.), to ad Chat Doctor.  You need to discuss with your attending physician about the above issues. Hope to have been helpful! Greetings!
