Inflammation of lymph nodes is mostly caused by infections with common pathogens such as Streptococcus haemolyticus and Staphylococcus aureus, which can invade from the patient’s skin or mucous membrane, or spread and invade from nearby lesions resulting in a disease that is a benign lesion of the lymph nodes. A small number of patients with mild disease can go down without taking measures if they are in good health and have an active immune system. For most patients, medical treatment is required to cure the disease, mainly medication: 1. Medication: commonly used drugs include anti-inflammatory antibiotics such as roxithromycin, cephalexin, penicillin, etc., as well as analgesic and antipyretic drugs such as ibuprofen, acetaminophen, etc., and antiviral drugs such as ganciclovir and adenosine monophosphate. All of the above drugs must be used under the guidance of a doctor and should not be taken on your own, nor should you increase or decrease the dosage, or even change the drug. Note that infants and children, pregnant and lactating women, and patients allergic to antibiotics are prohibited; 2. Other treatment: usually medication can be cured without surgery, while for infections that are not controlled in time and inflammatory abscesses in the lymph nodes, it is recommended to perform puncture to aspirate the pus, or incision and drainage, and supplemented with anti-inflammatory drugs for treatment. In addition, for inflammation caused by invasion of lymph nodes from other foci, treatment of the primary disease is required in addition to the treatment of lymphadenitis. At the same time, inflammation of lymph nodes is more obvious and painful, and patients may experience irritability and anxiety. Patients are required to maintain a stable and good state of mind, drink more water and avoid smoking, alcohol and spicy stimulating food to help the recovery of the disease. In some cases, the lymph nodes can become smaller or even disappear after treatment; in some cases, the inflammation of the lymph nodes has subsided, but the lymph nodes do not become smaller, but maintain the original size or the size at the time of inflammation. Special attention should be paid to differentiate it from malignant tumor of lymphatic system or metastatic cancer. If necessary, a lymph node puncture biopsy should be done, and it is better to take a complete lymph node for pathological examination to determine the nature of the disease.
