What is lymph node inflammation?
Lymph nodes are small, oval-shaped organs that contain immune cells to attack and kill foreign invaders, such as viruses. They’re an important part of the body’s immune system. Lymph nodes are also known as lymph glands.
Lymph nodes are found in various parts of the body, including theneck,armpits, andgroin。They’re linked by lymphatic vessels, which carry lymph throughout the body. Lymph is a clear fluid containingwhite blood cells (WBCs)and dead and diseased tissue for disposal. The primary function of lymph nodes is to harbor the body’s disease-fighting cells and to filter lymph before it reenters circulation.
When you’re sick and your lymph nodes send out disease-fighting cells and compounds, they may become inflamed or painful. The condition of having inflamed lymph nodes is referred to as lymphadenitis.
Lymph node inflammation can occur for a variety of reasons. Any infection or virus, including thecommon cold, can cause your lymph nodes toswell。Cancercan also cause lymph node inflammation. This includes blood cancer, such asleukemiaandlymphoma。
Lymph node inflammation can cause a variety of symptoms. Symptoms depend on the cause of the swelling and the location of the swollen lymph nodes.
Common symptoms accompanying lymph node inflammation include:
- tender, swollen lymph nodes in the neck, armpits, and groin
- upper respiratory symptoms, such as afever,runny nose, orsore throat
- limb swelling, which could indicatelymphatic system blockage

Treatment for lymph node inflammation depends on its cause. In some cases, treatment may not be necessary. For example, treatment is unlikely to be recommended for:
- healthy adults whose bodies are already conquering the infection
- children, whose active immune systems can result in frequent swelling
If treatment is required, it can vary from self-treatment to surgery and other therapies.
Self-treatment
Your doctor is likely to advise using a fever-reducingpainkiller, such asibuprofen(Advil, Motrin), along with a warm compress. Elevating the swollen area can also help relieve inflammation.
Medication
In other cases, a course of antibiotics may be used to help the body fight the infection that’s causing lymph node swelling.
Abscess draining
If a lymph node itself becomes infected, an abscess may form. Swelling will usually go down quickly when the abscess is drained. To do this, your doctor will first numb the area. Then they’ll make a small cut that allows the infected pus to escape. The area may be packed with gauze to ensure healing.
Cancer treatment
If your lymph node swelling is due to a cancerous tumor, there are a number of treatment options. These include surgery to remove the tumor,chemotherapy, andradiation。Your doctor will discuss each of these options, including their pros and cons, before starting your treatment.
