I’d like to say thank you to the people who responded about how I was feeling and my symptoms.
So I got checked by a doctor, like just standard stuff like bp, pulse ox and the heart sound thing aha, he said you look perfectly fine and that I haven’t had a heart attack as he’s seen many and especially not in a 21 year old. He said the pain in most likely some issues with the stomach and muscular with the arm.
I know it’s not like ECG or bloods but he was reassuring and certain of my state. I really appreciated his help and hopefully I can tackle my anxiety over having a heart attack.
