Swollen and Enlarged Jaw Lymph Nodes | Causes and Treatment

What are Lymph Nodes?

Lymph nodes can be found in various parts of a person’s body and are shaped like beans. These are part of a person’s lymphatic system, and they carry certain important elements to and from the bloodstream and the body’s tissues. Here are some of the areas where you can find lymph nodes, aside from under your jaw:

  • Lymph nodes can be found on your head and neck area, specifically on both sides of your neck, behind the ears, and under your jaw. These are all part of the group of lymph nodes that are called cervical lymph nodes.
  • Other lymph nodes can be found in the lower parts of your body like your chest, your armpits, abdomen, and your groin. These belong to the superficial lymph nodes group, the deep lymph nodes group, and the inguinal lymph nodes group.

Causes of Enlarged Jaw Lymph Nodes

Lymph nodes in any part of your body, including the ones under your jaw, sometimes swell for a number of reasons. These are usually due to injuries or illnesses or even due to a growth that can be found near this swollen lymph node. The reasons why they might swell include any of the following reasons:

  • When you have a swollen lymph node under your jaw, chances are, you may have a sore throat or a cold.
    Cuts and bites within the area of your head can also trigger the swelling of a lymph node under your jaw.
  • A swollen lymph node within the area of the neck, under the jaw, or other areas that can be found above your collarbone can also indicate a possible infection or tumor in your breasts, abdomen, lungs, or neck.

Treatments and Home Remedies for Swollen Jaw Lymph Nodes

Swollen lymph nodes in your jaw, behind your ears, or even in your mouth are just indicators of what is truly bothering your system. This means that when you want the swelling of a particular lymph node to disappear, you need to get to the root of the problem to do so.

  • When you are diagnosed with a viral infection, like measles or mumps, treat these problems and the swelling of your lymph nodes will recede in time.
  • Bacterial infections that make your lymph nodes swell can be treated with antibiotics.
  • Fevers, colds, and sore throats also need to be treated before the swelling of the lymph nodes that are under the jaw or behind the ears can begin to disappear.

      First of all if it is a lymph node, it is necessary to determine the cause of lymph node swelling. Your doctor must have given some medicine to reduce the size. Applying hot fomentation may help sometime to reduce the size, however you should talk to your doctor before applying hot fomentation on the swelling.

    I have swelling under my jaw on the left side of the neck. This has been for over a year now. It is painless but I am worried about it. The skin around the neck is dry and itchy. Can you suggest any remedies to this problem?
