Lymph node infection; Lymph gland infection; Localized lymphadenopathy

• Swollen, tender, or hard lymph nodes
• Red, tender skin over lymph node

Lymph nodes may feel rubbery if an abscess has formed.

The health care provider will perform a physical exam, which includes feeling your lymph nodes and looking for signs of injury or infection around any swollen lymph nodes.

A biopsy and culture of the affected area or node may reveal the cause of the inflammation. Blood cultures may reveal spread of infection to the bloodstream.
