Swollen Lymph Nodes in Neck One Side

Swollen lymph nodes in the neck on one side can be a cause for concern, as they can indicate an underlying health issue. While they often resolve on their own, it’s essential to understand the potential causes, symptoms, and treatment options associated with this condition. This article provides a comprehensive overview of swollen lymph nodes in the neck on one side, empowering readers to make informed decisions about their health.

What are Lymph Nodes?

Lymph nodes are small, bean-shaped organs that play a vital role in the body’s immune system. They are part of the lymphatic system, a network of vessels and tissues that circulates lymph fluid and helps remove waste and toxins from the body.

While lymph nodes are present throughout the body, they are most concentrated in the neck, armpits, and groin regions. These nodes act as filters, trapping bacteria, viruses, and other harmful substances that may be present in the lymph fluid.

Lymph nodes also contain immune cells, such as lymphocytes, which work to destroy any harmful substances trapped within the nodes. When lymph nodes become swollen, they fight off an infection or foreign substance.
