A swollen lymph node in the neck can be a concerning symptom, and it's essential to understand what it might mean for your health.

When a lymph node becomes swollen, it can be a sign of an underlying infection, inflammation, or even cancer.

In some cases, a swollen lymph node in the neck may be a minor issue that resolves on its own, but in other cases, it can be a sign of a more serious underlying condition. It's crucial to seek medical attention if you notice a swollen lymph node in your neck, especially if it's accompanied by other symptoms such as fever, sore throat, or difficulty swallowing.
