Does back pain mean cholecystitis? 1. Patients with acute cholecystitis may have pain in the right shoulder, which occurs because the inflammation can stimulate the right phrenic nerve endings during acute cholecystitis, resulting in a reflex pain sensation in the skin of the right shoulder. The phrenic nerve is composed of the 3rd-5th cervical nerves, mainly the 4th cervical nerve, and the 4th cervical nerve also divides into cutaneous branches, which are distributed in the skin of the shoulder. When the impulses from the right phrenic nerve terminal travel through the phrenic nerve to the 4th cervical ganglion, they affect the sensory nerve fibers distributed in the skin of the right shoulder, causing the cerebral cortex to misinterpret the pain sensation coming from the right shoulder. As a result, the patient feels pain in the right shoulder. 2, the right shoulder back pain caused by cholecystitis is a concomitant symptom, most cases should be abdominal pain caused by cholecystitis than the discharge pain in the back of the shoulder is obvious. The location of the abdominal pain caused by cholecystitis is the right upper abdomen, and the pressure pain at this location is also more obvious, while the discharge pain in the back of the shoulder is just a feeling, and touching the pressure will not cause the pain to increase. 3, cause back pain for many causes, gastroduodenal ulcer, pancreatic disease, etc. will also be manifested as low back pain. Muscle pain in the low back is also a common cause.
