Hi Ailee. Hopefully you have seen your doctor by now. This does point towards a possible gallbladder problem like gallstones. Liver and bile duct problems may be other possible causes. Dark urine with pale stools usually points to a condition where the flow of bile is affected. This occurs in gallstones along with the abdominal discomfort that you describe. Even if your symptoms have eased it is important that you have it checked up. Scans like an abdominal ultrasound may reveal any gallstones, if still present.
