Welcome to e health forum.
The common presentation due to gall bladder dysfunction 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.
Your symptoms are probably due to the presence of gall stones, as indicated by the ultrasound findings.
And, since your symptoms are very severe, surgery (cholecystectomy) would be the best treatment.
Hence you should consider to follow your doctors advice and undergo proper treatment at the earliest.
I hope this helps.
