Pancreatitis refers to the disease caused by the digestion of its own tissues by pancreatic fluid, with the main symptoms being pain, vomiting, and nausea. The pain is generally located in the upper left abdomen and can radiate to the left shoulder or left back. If it is biliary pancreatitis, there is generally pain in the upper right abdomen that gradually moves to the left side, may involve the entire abdomen, and radiates to the back in a belt-like manner. It often occurs suddenly after a full meal or drinking alcohol. The abdominal pain is very severe and unbearable, and active medication treatment should be used. (Specific medications should be used under the guidance of a physician.)
