I am a 21 yesr old male did the whole evaping thing for a year and a half and quit. I have been dealing with what feels like constant pressure on my chest for months starter after I quit, two days ago I woke up at about 5am couldn't get back to sleep so I started my day with some cleaning, come around 7 or so my whole left arm started feeling numb and my heart rate increased, this lasted for a few minutes then went away with me doing some deep breathing exercises, I thought maybe I slept on my arm and it just took a while for that blood flow to get moving so my heart had to work harder to get blood and oxygen to my arm. My arm is feeling sore and I have been worrying my self to death as to whether I may be experiencing some sort of heart disease, I work in a warehouse so I get alot of walking and exercise in on when I work and my eating habits are not that bad, I haven't had any back pain which I read is a symptom of multiple types of heart disease, but when I start thinking about the whole situation I get a slight numbing in my left arm and places along my neck and jaw. I can't imagine a 21 year old having heart problems but I am scared and I do not know what to do with not being able to afford health insurance I'm worried this is something serious and I won't be able to do anything about it.
