Gallbladder Info from Patient UK
The gallbladder lies under the liver on the right side of the upper abdomen. It is like a pouch which comes off the main bile duct and fills with bile. It is a 'reservoir' which stores bile. Pain from bilary colic can last just a few minutes, but more commonly lasts several hours. A severe pain may only happen once in your lifetime, or it may flare up from time to time.
