What Causes Swollen Lymph Nodes in Neck?
What causes neck swelling?
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:
Treatment for swollen lymph nodes from other causes depends on the cause:
ICD-10 code R59. 9 for Enlarged lymph nodes, unspecified is a medical classification as listed by WHO under the range - Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified .
The medical name for swollen lymph nodes is lymphadenopathy. In a child, a node is considered enlarged if it is more than 1 centimeter (0.4 inch) wide. The lymphatic system is a complex system of fluid drainage and transport, and immune response and disease resistance.

Swollen lymph nodes usually occur as a result of infection from bacteria or viruses. Rarely, swollen lymph nodes are caused by cancer. Your lymph nodes, also called lymph glands, play a vital role in your body's ability to fight off infections.
The above classification is not inclusive of several important nodal groups in the head and neck:superior mediastinal nodes.retropharyngeal nodes.parotid nodes.occipital nodes.posterior auricular (mastoid) nodes.facial nodes.
If swollen lymph nodes are only found in one area of your body, it's called localized swollen lymph nodes. And most of the time, you have a virus so there's no treatment truly needed and it will just run its course. The nodes will gradually shrink back to their normal size.
Normal lymph nodes are usually less than 1 cm in diameter and tend to be larger in adolescence than later in life. A clinically useful approach is to classify lymphadenopathy as localized when it involves only one region, such as the neck or axilla, and generalized when it involves more than one region [1].

Cervical lymphadenopathy is abnormal enlargement of lymph nodes (LNs) in the head and neck usually >1 cm. Most cases are benign and self-limited, however, the differential diagnosis is broad.
Lymphadenitis is the medical term for enlargement in one or more lymph nodes, usually due to infection. Lymph nodes are filled with white blood cells that help your body fight infections. When lymph nodes become infected, it's usually because an infection started somewhere else in your body.
