A painful ache in the right abdomen. The first symptom a person experiences when suffering from gallstones is a pain. The exact location can differ from person to person, but with most the ache will be centered on the gallbladder. This is located just under the liver, so the pain will be centered below the ribs on the right of your body. The intensity of the pain will depend on the intensity of the condition, ranging from very mild in the initial stages to a deep agony in the right abdomen if the condition is more serious.
