Which organ can refer pain to the right shoulder?

The gallbladder and liver are known to refer pain to the right shoulder due to a phenomenon called referred pain. This occurs because the nerves that supply these organs share pathways with nerves that supply other areas of the body, including the shoulder. The gallbladder, in particular, can be involved in conditions such as cholecystitis (inflammation of the gallbladder), where pain experienced in the upper right abdomen can radiate to the right shoulder area.

In addition, conditions affecting the liver, such as hepatitis or liver abscess, can also cause discomfort that may be felt in the shoulder region. The right phrenic nerve, which is associated with the diaphragm and located near these organs, can contribute to this referred pain as well. Therefore, when there are issues with the gallbladder or liver, it's not uncommon for patients to report pain that extends up to the right shoulder.

Understanding this connection is crucial for healthcare professionals in accurately diagnosing the source of shoulder pain, especially in contexts where abdominal issues are suspected.
