Hello user, As per your history there are 2 or 3 differentials which can be confirmed by ultrasonography of abdomen.1. The pain in right loin are mostly due to appendicitis, and this pain increases with leaning here and there, but imp fact opposing this is absence of vomiting !!2. The right sided pain may also be due to renal stones in the right kidney, which can be excluded by x-ray or ultrasonography.3. Intestinal problem like diverticulitis or any other problem, requiring colonoscopy to help to rule out the cause. I think most probably it's due to renal stone, but you should confirm it by ultrasonography or x-ray and visiting to your nearby gastroenterologist/nephrologist.hope my info helped you regards, Chat Doctor.
