Hello! Thank you for asking on HCM! I understand your concern, and would like to explain that your clinical symptomatology seems to be compatible with an extracardiac cause of your chest pain. It may be related to chest wall involvement (ribs, costocondral, intercostal muscle, skin, etc, inflammation) as well as a backbone disorder, or more profound involvement likie a pleural inflammation, etc. I recommend you to perform a medical consult by your doctor (GP or internist) for a careful physical examination, coupled by a resting ECG, chest X ray study, complete blood count, PCR, and if necessary cardiac ultrasound, etc. and additional blood tests. A painkiller medication would be of help. Hope to have been helpful to you! Greetings! Dr. Iliri
