new & unusual pain

Day before last I felt what was like muscle pull in my check and in my back. Maybe more like a pinched nerve because stretching activated it. One of the ways it was new is that it was directly in the center of my back between the shoulder blades on my spine. Most of my pinched nerves have been in the neck or around the left or right shoulder. The most unusal part of this is that it hurts a lot when I swallow food. Liquid is fine unless I swallow it hard/quick. Food makes me wince. The pain starts in the front middle of my chest and radiates to the back near the spine quickly. I think most people would stop eating if they had this kind of pain when the eat. Not me. : \

If this doesn't let up by tonight I'm making an appointment w/ a doctor. Although I'm not sure what they can do. I already searched google and didn't find any close to this.
