There is no data on how long back pain from cholecystitis lasts. Cholecystitis, refers to acute and chronic inflammation of the gallbladder caused by infection, parasites, stones, etc. It can manifest as sudden severe abdominal pain in the right upper abdomen and radiate to the right shoulder, and the pain can often be induced by satiety and eating greasy food, which can be combined with mild to moderate fever, nausea, vomiting, loss of appetite, jaundice, chills and high fever. When the inflammatory reaction of cholecystitis patients is more intense, it can invade the phrenic nerve, thus causing patients to experience back pain and other symptoms; when cholecystitis patients eat spicy and greasy foods such as fatty meat, it may induce an acute attack of cholecystitis, which stimulates the neuronal cells of the thoracic vertebrae area, leading to the body to experience symptoms of back pain. Patients with cholecystitis are advised to seek timely medical attention to clarify the cause of the disease, and then under the guidance of the doctor to carry out targeted treatment.
