But—what are lymph nodes? They are a vital part of the immune and lymphatic systems that help your body fight infections and disease. They are small, bean-shaped glands that carry nutrients, fluids, and waste between the bloodstream and body tissues. In general, lymph nodes are not painful, and you likely will not even feel them.

The problem is when lymph nodes become swollen. This condition is also sometimes called swollen glands, lymphadenitis, or lymphadenopathy.

Causes of Swollen Lymph Nodes

The other day I discovered a small bump on my neck. This bump turned out to be nothing serious—but sometimes it could be a sign of a greater problem. When lymph nodes swell in a particular location like the neck, it could indicate a minor infection like a common cold, or something more serious such as an injury, inflammation, or even cancer. The following are potential causes of swollen lymph nodes in the neck:

Viruses: Including herpes, human immunodeficiency virus (HIV), a common cold, adenovirus measles, chickenpox, and infectious mononucleosis (mono).

Bacteria: Including staphylococcus, streptococcus, cat scratch disease, syphilis, chlamydia, tuberculosis, and other sexually transmitted diseases.

Fungal diseases: Including histoplasmosis and coccidiomycosis.

How to Recognize Swollen Lymph Nodes

How can you tell if you have a swollen lymph node in the neck? Swollen lymph nodes can appear as small as a pea or as large as a cherry.

However, when they swell, they will double or triple in size to the point where they can be felt. What are other symptoms related to swollen lymph nodes glands?
