Hello: I'm glad to answer you Abdominal pain is a fairly common clinical symptom, which involves a wide range of complexity, some causes may be very mild, some are serious diseases, therefore, once the abdominal pain situation, you should correctly find out the causes of abdominal pain, so as not to affect the health. Abdominal pain is usually defined as pain that occurs in the front of the body, from the lower edge of the ribs to the pubic bone. Generally speaking, pain can be categorized as dull or sharp (hernia). Dull pain refers to a vague ache that occurs in most organs or viscera, while sharp pain refers to a pain that is so pronounced that the patient knows exactly where it is located, and is usually associated with an obstruction in a duct, e.g., a bile duct stone, or a blockage in the intestines. In most cases, there is a correspondence between abdominal lesions and the site of abdominal pain. Generally, the abdomen is divided into four regions, including upper right, lower right, upper left, and lower left, centered on the navel, and according to the site of abdominal pain, it can be divided into upper left abdominal pain, upper right abdominal pain, lower left abdominal pain, lower right abdominal pain, and abdominal pain in the center of the abdomen. If it is right upper abdominal pain, we must consider the liver, gallbladder, bile duct, pancreas, duodenum, right kidney, the right section of the large intestine and so on; right lower abdominal pain need to think of is the cecum, appendix, the right ovary and fallopian tube, the right ureter and so on; the left upper abdominal pain may be the stomach, spleen, pancreas, the left kidney, the left section of the large intestine; the left lower abdominal pain may be the sigmoid colon, the left ovary and fallopian tube, the left ureter and so on; if it is the navel pain, mainly indicates the small intestine disease. If the pain is around the navel, it is mainly indicated by small bowel disease. In addition, sometimes there may be widespread pain in the entire abdominal cavity, which is usually due to inflammation of the peritoneum due to some cause of irritation, such as: perforated ulcers, ruptured ectopic pregnancy, internal bleeding. It is worth noting that some abdominal pain will be shifted with the impact of the lesion, for example: the pain started in the center of the upper abdomen, and gradually moved to the lower right side within 24 hours and more and more pain, is an important sign of appendicitis; the pain site was originally in the upper right side, and gradually extends to the right back of the shoulder blade below the gall bladder, may be gallbladder, gallstones problem.
