Swollen Lymph Nodes under jaw one side Symptoms, Causes, Treatment

Lymph nodes are tiny glands that look like beans and are located all over the body. They are a component of the lymph system, and are responsible for transporting fluid (called lymph fluid), nutrients, and waste products between the tissues of the body and the circulatory system.

The immune system, which serves as the body's primary line of defence against illness, includes the lymphatic system as one of its key components. Lymph fluid passes through the lymph nodes, where special white blood cells known as lymphocytes capture viruses, bacteria, and other pathogens before destroying them.

Lymph nodes can be found individually or in clusters. They can be as big as an olive or as little as the head of a pin. Lymph nodes are found in clusters and can be palpated in the neck, groyne, and underarms. Typically, lymph nodes are not sensitive or painful. The body's majority of lymph nodes are not palpable.

Swollen Lymph Nodes under jaw one side

There are a number of potential causes of swollen lymph nodes under one side of the jaw. Lymph nodes are an integral part of the immune system that serve to filter and trap harmful pathogens and cells, including cancerous ones. When they become enlarged, they are usually reacting to an infection or inflammation in the body.

Swollen Lymph Nodes under jaw one side Symptoms, Causes, Treatment

Several typical causes of enlarged lymph nodes under one side of the jaw include:

Infectious diseases

Swollen lymph nodes can be brought on by bacterial or viral infections such tonsillitis, strep throat, influenza, and colds.

Dental difficulties

Swollen lymph nodes can also be a symptom of dental problems such gum disease, tooth decay, or abscessed teeth.


This infection, which is caused by a virus and is commonly referred to as "mono," can lead to symptoms such as swollen lymph nodes, a scratchy throat, fever, and exhaustion.

Salivary gland inflammation 

Swollen lymph nodes can also result from infections of the salivary glands, which are found beneath the jaw.


In a small percentage of cases, swollen lymph nodes under the jaw may be an indication of malignancy, particularly lymphoma or oral cancer.


The following signs and symptoms could be present when one side of the jaw has swollen lymph nodes:

  • Puffiness or a bulge under one side of the jawline
  • An affected area that is tender or painful
  • Swallowing or speaking may become difficult, particularly if edema is present
  • chills or a fever
  • Weakness or exhaustion
  • A swelling region that is surrounded by redness or warmth
  • Pain in the ears or head
  • Throat pain


When a problem, such as a trauma, infection, or tumour, develops in or around the lymph node, the lymph nodes frequently enlarge in a single location. Determining which lymph nodes are enlarged provides useful information. When you have a cold or an achy throat, you may notice that the glands on either side of your neck, under your chin, or behind your ears swell up. 


When the infection has been successfully treated, the swelling in the lymph nodes will typically go away. Taking prescription medications like antibiotics or antivirals may also reduce the edoema in the affected area.

When inflammation is present, doctors may recommend anti-inflammatory drugs.

If an underlying medical problem is the cause of the swollen lymph nodes, addressing the health issue should lessen the swelling.

Typical home remedies for the treatment of lymph node swelling include:

  • Using OTC pain relievers like acetaminophen or ibuprofen
  • Drinking plentiful fluids like water and fresh juices, applying warm moist compresses to the problematic area, and taking plenty of rest can all help the body recover from sickness.
