I was wondering if you found out what this is? I have the same issues. I get a pain in between the shoulder blades (right on the spine) and it radiates to the chest. I just had an upper gi done a few days ago. I have acid reflux and damage done (barrett's esp.) . I think the pains are from acid reflux but i am not sure. I also have a hernia which causes the acid reflux. I feel exactly like you explain it. Do you have an update?View Thread
