What is causing the swelling on one side of my neck? Swelling on one side of your neck is most likely caused by swollen lymph nodes in your neck. The cervical lymph nodes are located in the submental triangle, collecting lymph from the chin, floor of mouth and tip of tongue, and injecting them into the submandibular lymph nodes and digastric lymph nodes of the internal jugular vein. The cervical lymphatic tissue comes from the lymphatic drainage of the nose, sinuses, pharynx, larynx, mouth and face. Inflammation or cancer in these areas can invade or metastasize to the lymph nodes in various groups in the neck. Sometimes esophageal, chest, and even gastrointestinal cancers also metastasize here. Generally, the nature and cause of the swollen cervical lymph nodes can be identified and the possible primary lesions can be explored based on their location, size, texture, mobility, and the presence or absence of tenderness.

There are three causes of swollen lymph nodes in the neck: infection, tumor and other factors.

1. Infection factors

Bacterial - bacterial infections of the teeth, tonsils, face, or scalp, tuberculosis, syphilis, cat scratch disease, Lyme disease; Viral - herpetic stomatitis, infectious mononucleosis, HIV infection (AIDS); Parasitic - toxoplasmosis.

Unknown cause: Mucocutaneous lymph node syndrome (Kawasaki disease), subacute necrotizing lymphadenitis (Kikuchi disease).

2. Tumor Factors

Primary - Hodgkin's disease, non-Hodgkin's lymphoma, leukemia of white blood cells, especially lymphocytic leukemia; Secondary - cancer (metastatic tumors of the oral cavity, salivary glands, and nasopharynx), malignant melanoma, Ewing sarcoma, other mesenchymal tumors.

3. Other factors

Sarcoidosis, sinus histiocytosis, angiofollicular hyperplasia (including Castleman disease, angiolymphoid hyperplasia with eosinophils (Kimura disease), and related disorders)

If a cluster of spherical bumps appear on the neck, cervical tuberculosis should be considered first. People with nasopharyngeal carcinoma often develop enlarged lymph nodes deep in the neck. Swollen lymph nodes in the armpit often indicate a disease in the upper limbs or breasts. Swollen inguinal lymph nodes are a sign of infectious disease in the lower limbs and buttocks. In addition, people should not ignore the pathological reactions of lymph nodes caused by uterine cancer, testicular cancer, and rectal cancer. Enlarged left supraclavicular lymph nodes often indicate that cancer cells in the abdominal cavity have metastasized upward along the thoracic duct, such as liver cancer, stomach cancer, colon cancer, etc. Enlarged right supraclavicular lymph nodes often indicate that cancer cells in the chest cavity have metastasized upward along the right lymphatic vessels, such as lung cancer, esophageal cancer, etc. When suffering from lymphocytic leukemia, lymph nodes throughout the body will become swollen.
