A swollen lymph node under the jaw can be a cause for concern, but it’s often a common and treatable condition. The lymph nodes, also known as lymph glands, play a crucial role in our immune system, helping to fight off infections and diseases. When a lymph node becomes swollen, it can be a sign that the body is responding to an infection or inflammation in the nearby area.
Understanding Lymph Nodes
Before we dive into the possible causes and treatments for a swollen lymph node under the jaw, let’s take a closer look at what lymph nodes are and how they work. Lymph nodes are small, bean-shaped glands that are located throughout the body, including under the jaw, in the neck, armpits, and groin. They contain immune cells called lymphocytes, which help to fight off infections and diseases.
When the body detects an infection or inflammation, the lymph nodes near the affected area become activated, producing more immune cells to help fight off the infection. As a result, the lymph node can become swollen, which is usually a sign that the body is responding to the infection.

- Viral Infections: Viral infections such as the common cold, flu, or mononucleosis can cause swollen lymph nodes under the jaw.
