Welcome to e health forum.
It seems that you may be having cholecystitis or Inflammation of the gall bladder. It occurs when bile becomes trapped in the gallbladder.
The common presentation of such conditions include - Pain or tenderness under the rib cage on the right side , Pain between shoulder blades, Stools light or chalky colored, Indigestion after eating, especially fatty or greasy foods, Nausea, Dizziness, Bloating, Gas, Burping or belching, Feeling of fullness or food not digesting, Diarrhea (or alternating from soft to watery) and or Constipation.
Some measures that may help to control the symptoms include pain relievers and a low fat diet (when food can be tolerated).
You may consult with your doctor, who can get a ultrasound or a chest X ray, which may help in proper diagnosis and specific treatment.
I hope this helps.
