The gallbladder is on the right side of the abdomen, why do I have scapular pain during a gallbladder attack?

This is because both the gallbladder and scapula are close to the diaphragm. When acute cholecystitis occurs, inflammation can stimulate the phrenic nerve, which can cause radiating pain in the back or scapula. At the same time, acute cholecystitis can pull on the visceral nerve, which can also cause pain in the scapula. Therefore, scapular pain is likely to occur during an attack of cholecystitis.
