If the inflammation itself improves in time, the corresponding swollen lymph nodes may also improve quickly, and the whole course of the disease may only take a few days. If the inflammation itself is difficult to control, the swollen lymph nodes may take longer to heal. In relatively serious cases, if the inflammation is followed by serious lesions of the lymph nodes themselves, such as suppuration, not only oral medication but also surgery may be required to treat the suppuration of the lymph nodes, which may take longer.
