Recognizing swollen lymph nodes and other infection symptoms

Swollen lymph nodes, often in the neck or armpits, are a common sign of infection. These nodes can be tender to the touch and may cause pain. Other symptoms include fever, fatigue, and night sweats. These indicate the body is fighting an infection or dealing with inflammation. Lymph nodes are a key part of the immune system, acting as a first line of defense against pathogens. Early detection aids in timely treatment.
