Pediatric lymph node enlargement, if the child has no pressure pain in the lymph nodes, normal body temperature and no other discomfort, generally no special treatment is needed; if there is local pressure pain in the lymph nodes, along with symptoms of fever and cold, consider that it may be lymphadenitis, which requires timely anti-inflammatory and symptomatic treatment. Lymph nodes have immune function, some children are born with lymph nodes in the process of development, when invaded by bacteria and viruses, the lymph nodes will increase in size in order to resist pathogens, if the child’s body temperature is normal and the lymph nodes are not painful at this time, it is considered a normal phenomenon and does not require special treatment or therapy; if there are too many pathogens that exceed the lymph nodes’ ability to resist infection, the lymph nodes If the pathogens are too many and exceed the ability of the lymph nodes to resist infection, the lymph nodes will swell more obviously, accompanied by pain, and eventually develop into lymphadenitis, with local pressure pain and fever, etc. At this time, timely anti-inflammatory and symptomatic treatment is needed. Therefore, if the child has swollen lymph nodes, if the child’s temperature is normal, if the lymph nodes have not increased significantly in size and pain recently, and if the child has no other discomfort, it is considered a normal physiological phenomenon and does not need special treatment; if the child has fever, local pressure pain, redness and swelling, it is considered lymphadenitis and needs timely anti-inflammatory and other treatments.
