Swollen lymph nodes and normal blood count do not necessarily mean that there is a problem, but they are not completely non-serious either and require further examination at the hospital before a definitive conclusion can be made. If the lymph nodes are swollen and the blood count is normal when you go to the hospital, it only means that the lymph nodes are not inflamed temporarily, but the swollen lymph nodes are present. If it does not subside for a long time, a puncture should be done for pathological examination. If necessary, the lymph nodes can be surgically removed for pathological examination to determine whether the lymph nodes are benign or malignant in order to know whether the situation is serious. For example, if the lymph node is caused by lymphoma and the blood test is normal. Patients may have elevated blood tests only when they feel pain in the lymph nodes.
