Why does it hurt when you press your stomach?

Pain on pressure in the stomach is considered to be a disease of the abdominal organs, most often due to inflammation. Patients with acute appendicitis will present with pressure pain in the right lower abdomen, with rebound pain and myalgias, caused by inflammation spreading to the mural peritoneum. Patients with cholecystitis, especially in combination with gallbladder stones, will present with pain in the right upper abdomen. During acute attacks, there is significant pressure pain at the site of the intersection of the rib arch and the outer edge of the rectus abdominis muscle, which is also accompanied by fever and should be promptly treated with the surgical option. Patients with malignant tumors of the intestine, especially colorectal cancer, specifically include ascending colon, transverse colon, descending colon, and sigmoid colon. If the tumor is invasive and involves the plasma membrane layer, it may also show local pressure pain and even palpable masses, showing anemia, change in bowel habits and abnormal regularity. Fibrous colonoscopy can make a clear diagnosis, and for patients with early diagnosis, radical surgery should be chosen in time.
