A swollen lymph node under the jaw can be a concerning and puzzling symptom, often sparking worry about its underlying cause. As a medical professional with expertise in this area, I aim to provide a comprehensive overview of the potential causes, symptoms, and treatment options associated with this condition. Lymph nodes play a vital role in our immune system, acting as filters that trap pathogens, such as bacteria and viruses, and help to fight infections.
The lymph nodes are located throughout the body, including under the jaw, and are usually not palpable. However, when they become swollen or enlarged, it can be a sign of an underlying infection, inflammation, or other medical conditions. In this article, we will explore the various causes of swollen lymph nodes under the jaw, the symptoms that may accompany them, and the available treatment options.
