Lymphadenitis is a non-contagious disease that is caused by local soft tissue infections that result in reactive hyperplasia and enlargement of regional lymph nodes. Patients may also have fever and should be treated with intravenous anti-infection therapy. In the case of significant local abscess formation, surgery is also required to cut open the abscess and drain it. The symptoms of lymph node inflammation can also gradually improve, and mild patients can also be treated with local hot compresses that can promote the inflammation to subside. If there is significant pain, it can also be combined with the application of pain medication, a common drug is aminoglutethimide tablets. In addition, patients with lymphadenitis should also pay attention to nutrition during treatment and eat more high-protein foods, which can also promote recovery. Drink more water, eat more fresh vegetables and fruits, and vitamin-rich foods are also good for recovery.
