Swollen Lymph Nodes in Neck: Causes and Treatment (2023)

Lymph nodes are small, bean-shaped glands that store white blood cells and trap bacteria, viruses, and abnormal cells. You have lymph nodes spread throughout your body – in your neck, above your collarbone, under your jaws, under your armpits, and even in your groin.

Swollen lymph nodes in the neck are one of the natural ways your body responds to a bacterial or viral infection. When your lymph nodes swell, it’s usually a good thing. It means your lymph nodes are working effectively.

However, in extreme cases, your swollen lymph nodes may be a symptom of cancer.

Swollen Lymph Nodes in Neck: Causes and Treatment (1)

How do the Lymph Nodes work?

Lymph nodes are a part of your lymphatic glands that filters lymphatic fluid throughout the body.

These lymph glands act like a military roadblock that prevents harmful bacteria, dead cells, viruses, and abnormal cells from passing through the lymph channels and causing an infection.

So when your body has an infection, your small lymph glands may swell up to kill the foreign, invading organisms.

Just like blood vessels, the lymphatic system is made of distinct channels that travel throughout the body. So your neck, groin, and under your armpits may swell up in response to infection and tumors.

When you have an infection, the lymph nodes around the infection will swell up. For example, if a strep throat causes an infection, the lymph nodes in your neck may swell up. People with breast cancer may notice lymph nodes in their armpit.

Suppose you notice swollen lymph nodes around your body. In that case, the infection may have spread throughout your entire body, and it could signal something more severe like HIV, chickenpox, leukemia, or lymphoma.

Since your lymph nodes occur in clusters all over your body, you may feel a soft bump on the affected area when they are swollen.

When your neck swells, the lymph nodes in your neck have accumulated bacteria, viruses, dead cells, and other debris.

To fight off the harmful bacteria causing an infection, your body produces lymphocytes and sends other immune cells to your neck to fight off the harmful germs.

Lymph nodes also store lymphocytes and other immune cells that trap and remove germs, abnormal cells, dead cells, and waste from your body.

As we dig deeper into this article, you’ll discover what causes your swollen lymph nodes, their symptoms, and how to treat them.

Depending on the type of infection that causes your lymph nodes to swell, your swollen lymph nodes can also accompany other symptoms; these symptoms may include strep throat, common cold, and fever.

Diagnosing Swollen Lymph Nodes

Before your doctor diagnoses you with swollen lymph nodes, he may have to give you a physical examination.

Since he knows where the lymph nodes are in your body, he should pinpoint where you have swollen lymph nodes and what’s causing your nodes to swell.

Your doctor may also ask about your medical history.

If a physical test isn’t enough to diagnose your swollen lymph nodes, your doctor may recommend

  • X-ray scans
  • Biopsy: Surgical removal of lymph node tissue before it’s observed under the microscope.
  • Blood tests
  • Ultrasound scans: Using high-frequency sound waves to examine the internal body.
  • Magnetic resonance imaging scan (MRI): Using magnetic and radio waves to examine the internal body.
  • Positron emission tomography (PET) scan: Although it is used less commonly, the PET scan uses radioactive substances to view the chemical and metabolic processes in your body.

Your doctor may request a PET scan to identify heart diseases, certain cancers, and brain disorders.


Your lymph nodes are an essential part of your immune system. Just like your spleen, tonsils, and adenoids, your lymphatic system protects you from harmful organisms.

Your lymph nodes contain lymphocytes and other immune cells that fight bacteria, viruses, and other germs that can make you ill.

As your lymph nodes filter these infectious agents, your body produces more immune cells that accumulate at your lymph nodes and cause them to swell.

Your body comes in contact with many infectious agents, and any of these infections could cause your lymph nodes to swell.

Luckily, swollen lymph nodes are not usually serious. In fact, the swollen lymph nodes on your neck may disappear on their own after a few weeks. Besides, it’s super easy to treat swollen lymph nodes.

However, if your swollen lymph nodes don’t return to their original size 3 weeks after treatment, you need to consult your doctor.
