Anytime you have pain or even numbness
in your body you need to see a doctor. Chest pain
can be life threatening. It also might be a pinched nerve
, which is serious, but not immediately life threatening.
It's difficult without health insurance. You can just go to the emergency room.
You could also ask friends and coworkers to recommend a doctor (since you've had this condition for awhile, even though it seems to be serious). You can also search google for a free medical clinic near you.
