Symptoms
Gallstones may cause no signs or symptoms. If a gallstone lodges in a duct and causes a blockage, the resulting signs and symptoms may include:
- Sudden and rapidly intensifying pain in the upper right portion of your abdomen
- Sudden and rapidly intensifying pain in the center of your abdomen, just below your breastbone
- Back pain between your shoulder blades
- Pain in your right shoulder
- Nausea or vomiting
Gallstone pain may last several minutes to a few hours.
When to see a doctor
Make an appointment with your doctor if you have any signs or symptoms that worry you.
Seek immediate care if you develop signs and symptoms of a serious gallstone complication, such as:
- Abdominal pain so intense that you can't sit still or find a comfortable position
- Yellowing of your skin and the whites of your eyes
- High fever with chills
Types of gallstones
Types of gallstones that can form in the gallbladder include:
- Cholesterol gallstones. The most common type of gallstone, called a cholesterol gallstone, often appears yellow in color. These gallstones are composed mainly of undissolved cholesterol, but may contain other components.
- Pigment gallstones. These dark brown or black stones form when your bile contains too much bilirubin.
