I have a stabbing type pain in between my shoulder blades. feels like maybe food is getting stuck there. can this be acid reflux? what can i do to break up the food in there? thank you?

The pain location is too high for acid reflux (GERD); people have GERD usually complain of heartburn or retrosternal pain rather than upper back pain. You can try PPI over the counter such as Prilosec, Omeprazole or Nexium for a couple days as a trial. If pain is relieved you may have atypical case of GERD; if not improved or it gets worse, you should see your doctor or a GI specialist.
