Last couple years I have had upper back pain on rt. Chest feels heavy under right breast as well. Mam ok. Spine MRI us ok. Gallbladder is 9%. Cause?

Gallbladder Problem? I am assuming your gallbladder ejection fraction is 9%. If this is the case, then your gallbladder is not functioning like it should. This may be the cause of your problems. You should see a general surgeon for a full evaluation to determine if you would benefit from gallbladder removal. Good luck!
