Hello! Thank you for asking on HCM! I understand your concern, and could explain that all yuor 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 to perform 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 address the offending etiological cause. You need to discuss with your attending physician about the above issues. Hope to have been helpful! greetings! Dr. Iliri
