What should I do if I have swollen lymph nodes in my neck? Lymph nodes in the neck are mostly local lymph nodes in the lymphatic vessels of the head, organizing the lymph of the eyes, nose, lips, teeth, tongue and the floor of the mouth, and injecting the deep lymphatic cleanser in the upper and lower lateral neck. Inflammation or cancer in these parts can invade or metastasize to various groups of lymph nodes in the neck. Common causes are: 1. Inflammation: acute stage is characterized by redness, swelling, heat and pain, with rapid onset and the masses receding after anti-inflammation. In chronic cases, the disease is long, active, and without pressure pain. 2, tuberculosis: long duration, enlarged lymph nodes in the form of bunches, medium quality, movable, no pressure pain, can adhere to each other into a group, if caseous necrosis, ulceration will form a fistula. 3.Malignant lymphoma or metastatic malignant tumor: the lymph nodes are gradually enlarged, hard, poorly movable, no pressure pain, often one-sided, but can also be bilaterally involved. After parents find that their children have swollen lymph nodes in the neck, they should first go to the hospital for examination to determine the cause of their enlargement according to laboratory tests, such as routine blood tests, tuberculin test and chest X-ray. If the swollen lymph nodes are accompanied by pain, and the routine blood tests have an increased white blood cell count, it may be acute inflammation, and antibiotics should be applied promptly to control the infection, and the primary lesion should be actively searched and treated. If the history of the disease is long, not accompanied by pain, and not enlarged, and the routine blood count is not increased, it may be chronic stage, i.e. lymph node hyperplasia, and the application of antibiotics is not effective at this time. If only one or two lymph nodes are enlarged at this time, they can be left untreated for the time being and observed regularly. If there are more lymph nodes, a lymph node biopsy can be done to clarify the occurrence of other diseases. If there is a long history, no pain and no enlargement, no increase in white blood cell count in routine blood tests, positive tuberculin test and chest X-ray suggesting signs of tuberculosis, the presence of tuberculosis should be considered and anti-tuberculosis treatment should be given. If the lymph node biopsy is a tumor, the primary lesion should be identified and anti-tumor treatment should be administered in a timely manner.
