What does reactive lymph nodes mean?

Reactive lymph nodes refer to lymph nodes that have become enlarged or swollen in response to an infection or other inflammatory process in the body. Lymph nodes are small, bean-shaped structures that form part of the lymphatic system, which plays a crucial role in the body's immune response.

When the body encounters an infection, such as a bacterial or viral infection, the lymph nodes in the affected area or region may react and enlarge. This enlargement is a sign that the lymph nodes are actively involved in filtering and combating the infectious agents or foreign substances.

Reactive lymph nodes are typically characterized by:

1. Enlargement: The affected lymph nodes may become noticeably larger and more prominent than usual.

2. Tenderness: The enlarged lymph nodes may be tender or painful to the touch.

3. Mobility: Reactive lymph nodes are usually mobile and can move freely when gentle pressure is applied.

4. Non-fixed: They are not attached or fixed to surrounding tissues.

5. No signs of infection: Unlike cancerous or diseased lymph nodes, reactive lymph nodes do not typically exhibit signs of an underlying malignancy or serious medical condition.

Reactive lymph nodes are generally a normal response to infection or inflammation and usually return to their normal size once the infection or inflammatory process resolves. However, if the lymph nodes remain enlarged or exhibit any unusual characteristics, it is essential to consult a healthcare professional for further evaluation to rule out any underlying medical conditions.
