supraclavicular lymph nodes

The supraclavicular lymph nodes are a pair of lymph nodes found just above the clavicle or collar bone, toward the hollow of the neck. Lymph nodes are responsible for filtering the lymphatic fluid of unwanted debris and bacteria. They are located in strategic places in the body since they serve as early warning devices for the presence of infections. The lymphatic fluid from the head and neck regions is filtered by the lymph nodes in the neck area. Specific to the right supraclavicular lymph node is the drainage of the mid-section of the chest, esophagus, and lungs, while the left lymph node drains via the thoracic duct, the abdomen, and thorax. Swelling and pain in the lymph nodes are signs of an infection and sometimes, a malignancy. The swollen supraclavicular lymph nodes are easily felt as small painful lumps at the top of the collar bone. As the infection is treated, these lymph nodes revert back to their original size.
