Most of them have mesenteric lymph nodes, some as large as 25 mm in diameter, which often makes parents very nervous. Parents are often very nervous about this condition, and have been known to go on cephalosporin antibiotics because of it. What exactly is going on here? Is it necessary to take medication? Is it related to abdominal pain in children? Listen to what pediatricians have to say. Pediatricians want to tell you that lymph nodes have nothing to do with your child’s abdominal pain, so don’t give your child anti-inflammatory medication for this reason. Why do you say that? Because assuming you come in for an ultrasound when your child’s stomach is not hurting, you will find that the lymph node is still there, whether your stomach hurts or not, it has always been there. The purpose of the doctor having the ultrasound checked is to rule out other causes, such as a pediatric emergency called ‘intussusception’. About the enlarged lymph node on the ultrasound? Why is there this lymph node? Lymph nodes are small houses of lymphocytes. When a baby is not feeling well, the lymphocytes in the body will increase and gather to the problematic area. Most children have some swollen bumps on their neck when they have a cold, and these are the lymph nodes. You can feel your baby’s neck, will there be some lump-like things ah, this is the lymph nodes, so do not worry, this situation shows that your child’s immune function is normal. About mesenteric lymphadenitis? One thing to be aware of is that many doctors will give the diagnosis of mesenteric lymphadenitis to a child with abdominal pain, which seems reasonable. Let’s look at what is mesenteric lymphadenitis? Mesenteric lymphadenitis, like inflammation of lymph nodes in other areas, is a local infection that has spread to the surrounding lymph nodes, not a swollen lymph node that is lymphadenitis. 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 red, swollen, and painful, it means that the 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 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 in the right lower abdomen like appendicitis, mesenteric lymphadenitis mostly appears after a cold. In fact, most of the abdominal pain in children is caused by intestinal cramps, not mesenteric lymphadenitis. It only requires reasonable care and does not require medication.
