Most gallstones cause no symptoms at all and most people may not even be aware they have them. Gallstones that don't cause any symptoms usually don't need any treatment. They can disturb the lining of your gallbladder and they can get stuck in your bile duct causing an attack of abdominal(tummy) pain that:develops quickly, is severe, lasts about 1-3hrs before fading gradually and isn't helped by over-the-counter painkillers. Other symptoms of gallstones may include:feeling sick or vomiting, sweating, restlessness and jaundice(yellowing of your skin or the whites of your eyes).If you have any of these symptoms, see your doctor.
