During an annual check-up, the doctor typically feels the lymph nodes for swelling. what would swelling in the lymph nodes most likely indicate

ANSWER:

Swelling of lymph nodes may indicate an "infection" in the body. Lymph nodes when swollen usually indicate a "temporary infection". A vital function of the "lymph nodes" is to filter lymph fluid.

EXPLANATION:

Lymph nodes can be felt in the neck, groin and underarms and most lymph nodes cannot be felt. The lymph nodes occur in groups. A swollen lymph node may indicate a viral or a bacterial infection and can be treated using the correct medication. Usually a swollen lymph node "gets back to normal size" when the infection is treated completely.
