Can reflux gastritis cause some pain in between the shoulder blades in the upper back?

Possible: If you are experiencing acid reflux and back pain, you should talk to your doctor about what is going on. It might be related, however, if it's not, you do want to know what is causing your issues. There may be something going on that is totally unrelated to your reflux. If that is the case, you want to get it taken care of incase something else even more serious than acid reflux is going on. Art.
