Pain in chest and down left arm when i move neck?

Get evaluated.: I always think about "what's the worst this could be?" and with chest pain and left arm pain, i would like to see you have your heart evaluated pronto. But the fact that neck movement brings on left arm pain makes me wonder if you may have a problem in the cervical discs in your neck. Get the "worst possibility" ruled out first, and move on to the less dangerous things. Don't put this off. Lgromko.
