Depending on the location of the inflamed lymph nodes, patients need to consult different departments. Patients with swollen submandibular lymph nodes due to mouth ulcers need to consult the stomatology department. They can take watermelon cream tablets, swelling and pain relief, and gargle with light salt water to promote the healing of the ulcer wound and reduce the pain and inflammation of the lymph nodes. Second, patients with swollen axillary lymph nodes caused by acute mastitis can be seen in general surgery or breast surgery. Anti-infective drugs such as cefamandole or penicillin can be applied intravenously to control the acute infection of the breast and relieve the inflammation of the lymph nodes. Third, patients with enlarged lymph nodes in the inguinal region due to varicose veins in the lower extremities accompanied by phlebitis can be seen in vascular surgery. If necessary, the patient can surgically remove the varicose blood vessels to completely relieve the swollen lymph nodes.
