It is an important part of the immune system. When people refer to swollen glands in the neck, they are usually referring to swollen lymph nodes. Common areas where lymph nodes can be easily felt, especially if they are enlarged, are the groin, armpits (axilla), above the clavicle (supraclavicular), in the neck (cervical), and the back of the head just above hairline (occipital).Lymphatic systemillustrationSwollen lymph nodes in the groin - illustration Lymph nodes play an important part in the body's defense against infection. Swelling might occur even if the infection is trivial or not apparent. Swelling of lymph nodes generally results from localized or systemic infection, abscess formation, or malignancy. Common areas where the lymph nodes can be felt include the groin area, armpit, the neck, under the jaw and chin, behind the ears, and below the occiput (prominence on the back of the head). As a rule, when swelling appears suddenly and is painful, it is usually caused by injury or an infection.
