Most of them have large mesenteric lymph nodes, some as large as 25 mm in diameter, which often makes parents very nervous. This often makes parents very nervous. Some children go on cephalosporin antibiotics because of this. What exactly is going on here? Is it necessary to take medication? Is it related to the child’s abdominal pain? Lymph nodes have nothing to do with abdominal pain in children, so do not give your child anti-inflammatory medication for this reason. This is because assuming the child comes in for an ultrasound when there is no abdominal pain, the lymph node will still be there, and it will always be there whether you have abdominal pain or not. Some children who come back from 1 week of antibiotics to unrequested review find that there is no change in the lymph node and are often quite critical of the doctor’s treatment if the medication was prescribed by the doctor. If there is no relationship, why does the doctor want to check the ultrasound? The purpose of the ultrasound is to rule out a pediatric emergency called ‘intussusception’ and also to get a general idea of the entire abdominal cavity. This is because children are in the lymphatic active stage, lymph nodes are what ah, it is a small house of lymphocytes, lymphocytes more house will be big, otherwise can not live ah, huh. If you touch your child’s neck, most children will have some swollen bumps on their neck when they have a cold, and these are the lymph nodes. So don’t worry, it means your child’s immune function is normal. Let’s look at what is mesenteric lymphadenitis? Mesenteric lymphadenitis, like inflammation of lymph nodes in other areas, is a localized infection that spreads to the surrounding lymph nodes, not an inflammation of the lymph nodes that is swollen. For example, a child with abscessed tonsils will have swollen lymph nodes in the neck, which are the result of immune mobilization in the body to remove bacteria. If the lymph nodes are then red, swollen, and hot, it means that bacteria have infected the lymph nodes, and this is lymphadenitis. Therefore, mesenteric lymphadenitis will have abdominal pain, but most of it is constant pain, not relieved after the stool, there must be a high fever, because it is caused by inflammation? There is pressure pain or even rebound pain in the abdomen, especially like acute appendicitis, only the pressure pain point is not fixed like appendicitis, the right lower abdomen, mostly after the cold. The majority of abdominal pain in children is caused by intestinal cramps, not mesenteric lymphadenitis. The purpose of all this is to make sure that you don’t get nervous about the ultrasound finding of large intra-abdominal lymph nodes, which do not require special treatment. If it is a particularly large lymph node, it should be reviewed in conjunction with the child’s condition. The paroxysmal abdominal pain that often occurs in children is mostly intestinal spasm, which is related to the child’s diet and living habits, and does not require medication.
