The pain is usually mild in nature and can be improved by rest or massage. If the abdominal pain is caused by inflammation of the abdominal cavity, it is common to have cholecystitis or appendicitis. Patients will experience pain in the right upper abdomen or right lower abdomen. After clarifying the cause, they need to stop the pain quickly and can take oral pain medication. It is also necessary to go to the hospital for examination, and antibiotics can be infused to control the inflammation. And active preoperative preparation is needed, laparoscopic gallbladder or laparoscopic appendectomy is recommended. If the abdominal pain is caused by tumor, such as gastric cancer or colon cancer, the pain appears in the upper or lower abdomen. After gastroscopy, colonoscopy and abdominal CT examination are performed to clarify the diagnosis, radical tumor surgery should be performed.
