Sharp Pains In Chest Area

I don't know where to turn as i'm currently out of health insurance, recently graduated college and looking for a job with coverage. I have been a bit of a hypochrondiac lately, probably because I don't have insurance and everything seems so severe when its even the slightest pain.

Lately, i've been getting these sharp, sometimes shooting pains in my chest area but not really around the heart, only occasionally. The pain sometimes extends down to the top of my stomach. When I get distracted and don't think about it, the pain seems to not bother me, if it is there at all, but then I remember it and it comes back almost instantly. It's not that bad, but it worries me. I'm only 23 and have never had any health problems before. Does anyone know what this might be? I have been researching it all day and nothing has come up that sounds like it fits what i'm feeling. Please help if you can, thanks.
