Hello! Thank you for the query. Upper right side of the abdomen can be caused by gallstones or pancreas disease. Especially if the pain appears after a meal (usually fat meal), nausea and vomiting appears. Fever can indicate an inflammation of gallbladder. Cramps and bowel movements problem can also indicate bowels obstruction. It is more possible if you have had any constipation before, diarrhea, weight lost, blood in stool. Sometimes peptic ulcer can also give such symptoms. I suggest you to visit your doctor and have some tests done. Abdominal ultrasound, blood work, liver tests (AST,ALT,GGTP), bilirubin, amylase, urine amylase, urine analysis and abdominal X-ray done. If this tests will be negative, gastroscopy and colonoscopy should be considered. In a meanwhile you should avoid fatty foods, spicy foods, alcohol, coffee. Hot bath, Metamizole, Buscolyzine can ease the pain. Hope this will help. Regards.
