Pain in the lymph nodes

Introduction Superficial lymph nodes are distributed in groups. Each group of lymph nodes receives a certain part of lymph, such as lymph nodes in the ear and mastoid areas, and lymphocytes from the scalp. The submandibular lymph nodes receive the bottom of the mouth, buccal mucosa, and gums. The fluid, the axillary lymph nodes, collect the lymph in the tissue, lips and tongue in the lower triangular zone. The deep cervical lymph nodes collect lymph in the nasopharynx, larynx, trachea, thyroid gland, etc. The right supraclavicular lymph node receives the lymphatic fluid in the trachea, pleura, lung, etc., and the left supraclavicular lymph node receives the lymph in the esophagus, gastrointestinal and other organs. The upper part of the trunk, the breast, the chest wall, etc. are lymphatic fluids that flow back into the axillary lymph nodes. If there is an inflammatory reaction or cancer in the corresponding part, lymphadenopathy and pain may occur.

Cause

Chronic lymphadenitis

Most of them have obvious infections, and often have localized lymphadenopathy, pain and tenderness, generally no more than 2 to 3 cm in diameter, and will shrink after anti-inflammatory treatment. Inguinal lymphadenopathy, especially long-standing and unchanged flat lymph nodes, is of great significance. However, there is no obvious cause of swelling of the neck and supraclavicular lymph nodes, which marks the systemic lymphoproliferative disease, which should be taken seriously and further examined and confirmed.

Tuberculous lymphadenitis

There are fever, sweating, fatigue, and increased blood sedimentation, which are more common in young adults. Often accompanied by tuberculosis, the lymph nodes are uneven in texture, some are lighter (cheese-like), some are hard (fibrosis or calcification), and adhere to each other, and adhere to the skin, so the activity is poor. This type of patient is tuberculin test and blood tuberculosis antibody positive.

First, physical examination

Collecting a medical history can initially diagnose the disease and also have a preliminary judgment on the nature of the disease.

Second, laboratory inspection

Laboratory examinations must be summarized and analyzed based on objective materials and medical examinations, and several possible diagnostics are proposed. Further consideration is given to those examinations to confirm the diagnosis. Experiments for lymph node pain are often performed. The room examination has blood routine, tumor tomography, lymph imaging and the like.

Differential diagnosis

Lymph node pain needs to be differentiated from lymphadenopathy. Lymph node enlargement is a phenomenon in which the lymph nodes become enlarged due to internal cell proliferation or tumor cell infiltration. Common clinical signs. It can be found by touching the submandibular, neck, supraclavicular fossa, axilla, and groin, but swollen lymph nodes in the hilar, mediastinum, retroperitoneum, and mesentery can be found by X-ray, CT, and B-ultrasound. Benign swelling is generally associated with pain.
