How long it takes for lymphadenitis to subside depends on the cause, the patient’s physical condition, whether it is treated promptly, and the degree of local infection, and cannot be generalized. Acute lymphadenitis caused by bacterial infection is more common and can be characterized by localized redness, pain, swelling and pressure pain in the lymph nodes. If the patient is in good health and the infection of the lymph nodes is mild, the inflammation can gradually subside after 3-7 days in most patients through continuous external application of 50% magnesium sulfate or ichthyolite ointment and oral antibiotics such as cephalosporin anti-infective treatment. If the patient is in poor health and the lymph nodes are heavily infected, and if they are also combined with acute purulent infection, anti-infective treatment should be accompanied by local abscess incision and drainage at the doctor’s discretion, with a general recovery time of 2-3 weeks. In case of chronic lymphadenitis, the swollen lymph nodes usually take 2-3 months to subside; if the swollen and red lymph nodes are caused by other reasons, such as tuberculosis, virus, tumor, etc., the treatment should be done accordingly according to the causative cause, and the time is uncertain. In addition, during the illness, patients are advised to avoid eating spicy and irritating foods, such as chili, ginger and garlic, which are not conducive to disease recovery.
