Swollen Lymph nodes
The lymph nodes are part of the lymphatic system that is part of the immune system. Lymph nodes often swell in response to infection or disease. Sometimes this is somewhat inaccurately called "swollen glands" (lymph nodes are not glands; they do not secrete anything). The most common locations of lymph node swelling are in the neck, groin and underarm, though many other locations are possible.
Numerous conditions and infections can cause swollen lymph nodes including:
Common cold
Infections
Viruses
