Abdominal pain is a very common symptom in children and has many causes. We should be good at identifying all types of abdominal pain to avoid delaying the condition of the child. Common pediatric abdominal pain is briefly described as follows: young children often can not accurately tell the location of the pain, then parents can take advantage of the child’s quiet sleep, gently touch the abdominal examination, may get some very useful clues. The child will have a painful facial expression or quickly push the examiner’s hand away when the painful spot is touched. If the pain is in the lower right abdomen and the symptoms are abdominal pain followed by fever, vomiting, and curling of the right lower extremity, appendicitis should be considered; if fever and coughing occur first, followed by pain in the lower right abdomen, lobar pneumonia is a possibility. If the abdominal pain is located in the upper abdomen and is paroxysmal and severe, or even rolling in pain, it is likely to be biliary ascariasis. If the abdominal pain is located around the navel in paroxysms, but is not severe, and is lively and free after a burst of pain, the possibility of suffering from intestinal roundworm disease is high. When there are many roundworms and they gather into a mass, they will block the intestinal cavity and cause severe abdominal pain, accompanied by vomiting and a mass that can be felt in the abdomen, intestinal obstruction by roundworms needs to be considered. Sometimes the abdominal pain has no fixed location, but there are gurgling intestinal sounds, diarrhea at the first pain, stools with pus and blood and snot-like mucus, and eating unclean food before the onset of the disease, then the possibility of having enteritis and bacillary dysentery is high. Improper feeding and overfeeding of children can also cause abdominal pain. Sometimes the pain is more intense and has no fixed site. When a burst of pain is present, strips can be touched in the abdomen, which may be intestinal cramps. Children who suffer from wind chill may also have vague pain in the upper abdomen. At this time, children often like to pull the hands of parents to gently massage the painful area. When this happens, it is important to keep the abdomen warm. If an infant aged 4-18 months suddenly cries and fusses, and after 2-3 minutes everything is normal again, but the spirit is poor and he wants to sleep, and the crying is repeated after an interval of about 10-15 minutes, intussusception is more likely. Children with a history of constipation may also have sudden abdominal pain, which may be more intense, with pressure pain on the left side of the abdomen and lower abdomen, and may be relieved after defecation. If any of the above abdominal pain is accompanied by fever, vomiting, diarrhea and other symptoms, it is necessary to send to the hospital for consultation. Parents should take special care to see a pediatric surgeon first to rule out surgical conditions that require immediate surgery to avoid delay and serious consequences. Parents should also be reminded not to give painkillers to their children until the diagnosis is clear, as this may mask the symptoms and lead to serious problems.
