Pain, particularly shoulder pain, is a social and economic problem worldwide. Although visceral pathology is not yet taken into account in the diagnosis of these pains, it is likely that on numerous occasions the hepatobiliary visceral condition causes referred pain in the metameric area belonging to the shoulder due to the involvement of the phrenic nerve. Therefore, the aim of this project is to study the response of treatment by neuromodulation of the phrenic nerve for shoulder pain in patients with associated hepatobiliary pathologies, assessing the possible visceral involvement in the symptomatology.
