Stomach pain with lumbago can be treated differently depending on the cause of the patient’s pain. First, gallbladder stones accompanied by acute cholecystitis, patients will experience pain and discomfort in the right upper abdomen, accompanied by radiating pain in the lower back. At this time, the patient is advised to take active anti-infection, liver protection and rehydration support treatment. After the patient’s inflammation is completely controlled, it is recommended that the patient undergoes cholecystectomy as soon as possible to avoid recurrent attacks of gallbladder inflammation, which may affect the patient’s normal life. Second, acute necrotizing pancreatitis with a large amount of pancreatic enzyme exudation will cause peripancreatic tissue erosion, resulting in pain in the left side of the abdomen, accompanied by soreness and discomfort in the lower back. At this time, patients can use octreotide as soon as possible to inhibit the secretion of pancreatic enzymes, rehydrate a lot, dilute the toxins in the body, and strengthen anti-infection treatment. If necessary, ultrasound-guided puncture and drainage of the inflammatory fluid in the abdominal cavity can reduce the patient’s abdominal pain and the swelling and discomfort of the low back.
