Hi, I wonder if anyone can help reassure me until tomorrow when I will probably go to the doctors... I'm a 21 year old male in the UK. For a few years I've had chest pains come and go for a few weeks at a time, then go away again. I've always put it down to heartburn/indigestion, but recently I'm becoming more convinced it's cardiovascular/circulation related and it's starting to really worry me. Googling symptoms tells me that I'm having a heart attack etc and that scares me too despite not believing it, so unless this actually is likely, I'd rather not be made to worry! I've seen doctors before about this and they listen to my heart and breathing before sending me on my way. However I feel like it's worse this time round. The pains happen in the left side of my chest normally. They are sharp pains and seem to occur randomly only for a few seconds at a time during these periods of a few weeks where I get these pains. They aren't severe but more than an irritation (let's say 3-5 on a scale 1 to 10). Afterwards I can feel a dull feeling (not pain, more like ache but that's still not quite right) in my chest, generally left side. Sometimes the ache-like feeling happens in my neck too. Today I got a couple of rushing feelings shoot down my left arm leaving a couple of fingers feeling tingly, and my arm feeling cold (but not numb) for a few minutes, as well as the ache-like feeling in my chest and left shoulder. My father and grandfather have high cholesterol and I've never been tested so potentially that's a cause? My other grandfather is type 2 diabetic and had a triple heart bypass when he was about 65 (as a guess). I've also played with the idea that it's stress-induced (I've got exams next week), due to lack of exercise (I don't really get any but I'm, if anything, slightly underweight), or to my diet which isn't terrible but has more fat and sugar than it should I expect. Currently I have no medical history personally. As I said before, I'm worried enough to go to the doctors tomorrow, but it's midnight here so I can't really do much about it right now. Medical things scare me a lot so please try to avoid setting me off in a panic because I'm sure that won't help, and if it is related to the stress I'm feeling, will make it worse. Any advice would be appreciated, thanks.
