I have heart conditions that run in my family, and my father has A. Fib. My symptoms have been pain in ankles/feet while resting, cold extremeties, discolouration, severe chest pains, tightness in chest, pain in chest, heart burn, tingling/numbness in left arm, palpitations. I am 22, 511 and 140-145 lbs.
Hello! Thank you for asking on Chat Doctor! I read your question carefully and understand your concern. Your symptoms seem to be related to anxiety. Your family history for atrial fibrillation doesn't seem to be related to your symptomatology. Has anybody besides you noticed the skin discoloration of your limbs? You are too young for such cardiac disorders. Anyway, a metabolic disorder (like thyroid dysfunction, etc.) can not be excluded. I recommend consulting with your GP for a careful physical examination and a complete check-up
