Hello my name is Marcos. Today while I was in a class early in the morning I started feeling severe pain in my left shoulder. After the class(which lasted 8 hours) the pain only became worse. The pain is above my left shoulder. Then for a couple hours the pain spread slightly into my right shoulder. while the pain isn't as severe anymore it's still there. I also felt irritable and kinda lightheaded all day.

Now I was researching into the causes a little and found that some places said these might be symptoms of a heart attack. However, I'm also the kind of person who kind of "feels" some symptoms because I've recently read about them and they're not always really rare.

I'm also under depression medication(paroxetine), which was partly due to getting some minor panic attacks, and have felt a few smaller ones lately.

I just turned 21, non smoker, and drink maybe once a year. Another problem is I come from a family who doesn't really visit a doctor unless it's become dire.

Could it have possibly been that I almost had a heart attack, some sort of cardiac problem, or something completely different?
