Well my heart has been feeling kinda weird lately, like my heart is beating to fast or to hard, while having this all of a sudden i get this cold sensation
through my body like a cool breeze going thru me and i feel like i am going to faint, and i feel like my heart is going to stop but it goes away after a few seconds or when i stand back up. i feel a small tightness around my chest
heart area. i am a 21 year old male 220 pounds. 5 feet 10 Any info would be great, Thank you.
