Without a complete evaluation it may not be possible to detect the exact cause of your symptoms. The common causes of pain in right upper quadrant are duodenal ulcer, gallstones, appendicitis, kidney stones, panacreatitis; Crohn’s disease etc.Each of these conditions has other associated symptoms which may help in determining the cause of your illness. Consult a primary care physician. He may further refer you to a specialist based on clinical findings. Do write to me again.
Best of luck!
