Swollen lymph nodes may signal infection or illness, but it is not necessarily a cause for alarm. Your body’s lymphatic system works to keep infections and other illnesses at bay by carrying fluid, waste, and specialized white blood cells called lymphocytes throughout your body. When lymphocytes become too numerous in one area of the body, such as the neck, armpit, and groin area, some nearby lymph nodes may become swollen. This is often a sign of an infection or illness somewhere in the body.

It’s important to remember that swollen lymph nodes can be caused by a variety of things besides an infection; allergies and autoimmune conditions can also cause the nodes to swell up. Therefore it is important to consult with your healthcare provider if you notice swollen lymph nodes in order to determine their underlying cause. This guide will provide people with an overview on what could be causing their swollen lymph nodes and what treatments are available depending on their diagnosis.

What are Lymph Nodes?

Lymph nodes are small, bean-shaped glands located throughout the body. They are part of the lymphatic system, an important part of the immune system that helps to fight off infections and other illnesses. Lymph nodes contain lymphocytes, a white blood cell that helps protect the body against bacteria and viruses.

When an infection occurs in or near a lymph node, it will become swollen to help capture and destroy bacteria or viruses that have entered the body.

In general, enlargement of the lymph nodes is known as lymphadenopathy. This can be caused by various factors including viruses, bacterial infections such as strep throat, cancerous cells, autoimmune disorders such as lupus, or other medical conditions. Swollen lymph nodes can occur in any area where there are nodes present; however they are more likely to be seen in the neck, groin or armpits.

  • Swollen lymph nodes can vary in size from pea-sized lumps to larger lumps about the size of a golf ball.
  • Additionally they may be tender when touched and can move around under your skin if they aren’t tender too much when pressed upon.

It’s important to consult your doctor if you notice swollen lymph nodes as they may be an indication of something more serious than just an infection or illness such as certain types of cancer. In any case, your doctor should be able to tell what additional causes may have caused your swollen lymph nodes so you can pursue treatment accordingly and get back on track with better health overall.

Causes of Swollen Lymph Nodes

Swollen lymph nodes can be a sign of an underlying infection or illness. They can be caused by a variety of different things, ranging from a virus or bacterial infection to an autoimmune disorder or cancer. Knowing the potential causes of swollen lymph nodes can help you identify and treat the underlying condition.

In this article, we’ll explore the potential causes of swollen lymph nodes:

  • Virus or bacterial infection
  • Autoimmune disorder
  • Cancer


Swollen lymph nodes are usually caused by a localized infection resulting from bacteria, viruses, or other microorganisms. Common infections that may cause swollen lymph nodes include:

  • Ear Infections – Ear infections (otitis media and external) can cause swollen lymph nodes in the area of the neck where the ear meets the head.
  • Sore Throat – Swollen lymph nodes in the neck are common when someone has strep throat or other throat infection.
  • Respiratory Infections – A viral illness such as a cold or the flu can cause swollen lymph nodes in the chest and neck area. This is because viruses often spread to nearby organs and tissue, including those of the immune system.
  • Cuts and Scrapes – Any break in the skin can lead to a localized infection that causes swelling of nearby lymph nodes. A small cut on your finger or an animal bite, for example, could both result in swollen lymph nodes in your arm pit as bacteria spreads to that area.
  • Skin Conditions – If you develop eczema, psoriasis, chickenpox and even some forms of acne you may experience swelling of nearby tissues including your local lymph node clusters as your body’s immune system responds to control these places on skin affected by these conditions.
  • Sexually Transmitted Diseases (STD) – Some types of sexually transmitted diseases such as HIV/AIDS and hepatitis may cause swelling of local lymph node clusters near primary sites where they entered into your body.

Certain types of cancer such as lymphoma, leukemia, and multiple myeloma can cause swollen lymph nodes. The lymphatic system is a network of organs, glands and vessels that help your body fight infection, illness and disease. When cancer cells accumulate in the lymph nodes they can cause the tissue to swell and become enlarged. You may also experience unexplained weight loss or night sweats in addition to swollen lymph nodes if you have certain types of cancer.

Similarly, other cancers such as breast cancer or testicular cancer may cause swelling in nearby tissues which can be confused with swollen lymph nodes. If you experience any swelling near any major organs, it is important to consult your healthcare provider for further evaluation.

Autoimmune Disorders

Swollen lymph nodes can be a symptom of several different autoimmune disorders, including rheumatoid arthritis, lupus, and multiple sclerosis (MS). Autoimmune disorders are a group of conditions where the body’s own healthy tissues are mistakenly attacked, leading to inflammation and swelling.

In rheumatoid arthritis, the patient experiences stiffness and pain in their joints due to an inflammation of their synovial membrane which produces joint lining fluid that lubricates skin. Lupus is an autoimmune disorder that causes inflammation in several areas including the skin, heart, and lungs. Multiple sclerosis is caused by attacks on the brain or spinal cord from a combination of malfunctioning nerve signals from the immune system.

Other common symptoms of autoimmune disorders include:

  • Fever
  • Fatigue
  • Muscle aches and pains
  • Difficulty breathing or moving around due to pain or weakness
  • Skin lesions/ dryness or wounds that don’t heal easily

A medical professional may order tests for certain markers related to autoimmune diseases such as anti-nuclear antibodies (ANA) tests which can help to detect lupus. Treatment for swollen lymph nodes due to an autoimmune disorder typically depends on what type of disorder is causing it and usually involves a combination of medications and lifestyle changes.

Diagnosis of Swollen Lymph Nodes

Swollen lymph nodes are often a sign of an underlying medical condition. In order to diagnose the condition, it is important to understand what causes swollen lymph nodes and what other symptoms they can signify.

Physical Exam

A physical exam is the first step to diagnosing swollen lymph nodes. The doctor or nurse may look at and feel your lymph nodes to determine the size, consistency, and location of any swollen area. In some cases, it is necessary for the patient to remove clothing for a more thorough examination.

Upon examination, the doctor may look for other signs of swelling that can help diagnose underlying medical conditions. These signs include:

  • Fever
  • Night sweats
  • Unexplained weight loss
  • Rash
  • Fatigue

If additional information and diagnosis are needed, a medical professional may recommend further testing. These tests can include:

  • Blood work to test for infection or screen for cancer
  • Imaging studies such as CT scan or ultrasound of the area
  • Fine needle aspiration (FNA) biopsy
  • Skin biopsy in order to identify any possible underlying causes or treatable infections or cancers.

After results have been obtained from any recommended testing procedures, the doctor discusses their findings with you in order to create an individual care plan that will best manage your symptoms and target any underlying causes identified during testing.

Imaging Tests

If a physical exam reveals swollen lymph nodes, medical imaging may be recommended in order to confirm a diagnosis. These tests can provide information about the size and location of the lymph nodes, and often help identify the underlying cause. Common imaging techniques used to study swollen lymph nodes include:

  • Ultrasound: Ultrasound uses sound waves to create images of internal organs including the lymph nodes, allowing healthcare providers to measure their size and detect fluid-filled cysts or tumors.
  • Computed Tomography Scan (CT Scan): A CT scan uses X-ray views taken from different angles in order to construct an image of internal structures such as organs and lymph nodes. It can often reveal if there are any growths or abnormalities present without having to perform major surgery.
  • Magnetic Resonance Imaging (MRI): An MRI can detect small changes within the body’s tissues that wouldn’t show up on an x-ray or CT scan, allowing for a more detailed assessment of swollen lymph nodes than other imaging techniques. It can also generate detailed 3D images which can help distinguish between cancerous and noncancerous lesions.
  • Positron Emission Tomography (PET) Scan: A PET scan detects areas of abnormal metabolism within the body by utilizing radioactive materials that specifically target certain structures such as tumors or abnormal cells within the lymphatic system or other organs near them—providing healthcare professionals with valuable insight into disease progression or response to treatment plans.

Blood Tests

Blood tests are often administered to diagnose swollen lymph nodes. A complete blood count (CBC) will help detect blood toxemia, which occurs when an abnormally high amount of toxins, proteins, or cells of a particular type are present in the bloodstream. An elevated white blood cell count may indicate the presence of infection or disease that is affecting the lymph nodes. Further testing may be done to determine if there is a bacterial/viral infection present within the body as infections can cause inflamed lymph nodes.

More specialized tests may also help identify potential causes for enlarged lymph nodes, such as:

  • Rheumatoid panel and sedimentation rate (ESR) tests to identify the presence of rheumatoid arthritis and infectious diseases like mononucleosis.
  • Liver function and thyroid function tests can be administered to evaluate other potential causes such as liver problems or hypothyroidism.

Treatment of Swollen Lymph Nodes

Swollen lymph nodes can be uncomfortable and sometimes painful, and they can be indicative of an underlying health issue. Fortunately, there are a variety of treatments available to help reduce the swelling and relieve symptoms.

This section will discuss the different types of treatments available for swollen lymph nodes:


Antibiotics are a common treatment for swollen lymph nodes. If bacterial infection is suspected as the cause of your swollen lymph nodes, a doctor may prescribe antibiotics such as amoxicillin or cefazolin. Some physicians will also prescribe antibiotics prophylactically, to reduce the chance of recurrent infections. It is important to take the entire course of antibiotics prescribed by your doctor even if you begin to feel better after taking only a few pills, in order to ensure that the infection is completely eliminated.

Your doctor may further recommend additional treatments depending on your overall health and the type of infection that caused the swelling in your lymph nodes. These treatments could include:

  • Warm compresses applied to the affected area
  • Pain relievers
  • Over-the-counter medications meant to reduce fever and inflammation

If your immune system is weakened due to an underlying medical condition, you may need other forms of treatment such as anti-inflammatories. Finally, if a fungal or parasitic virus is responsible for your swollen lymph nodes, your doctor can prescribe medications that can help reduce symptoms and lessen swelling associated with these types of infections.


Surgery is a treatment option for swollen lymph nodes if necessary. The type of surgery will depend on the cause of the swollen lymph nodes and may include:

  • Lymph node biopsy: This procedure involves removing a sample of lymph node tissue to have it tested for cancer, infections or other conditions.
  • Lymph node excision or resection: This operation removes some or all of the infected or cancerous lymph nodes, which helps with symptom relief.
  • Sentinel node biopsy: This procedure involves removing one or more lymph nodes in order to look for cancerous cells that may have spread from another area.
  • Axillary node dissection: During this procedure, all of the underarm lymph nodes are removed in order to check for the presence of cancerous cells.

Radiation Therapy

Radiation therapy uses high-powered beams of energy, such as X-rays and protons, to kill cancer cells. Radiation therapy may also be used to reduce the size of swollen lymph nodes and ease the symptoms of swollen lymph nodes caused by cancer. Radiation therapy often acts quickly in reducing the size of swollen lymph nodes, making it a good choice for someone whose symptoms need relief right away. It can also delay or stop tumor growth in some cases.

Radiation therapy is typically done over several weeks and may cause side effects such as skin redness. It’s important to talk with your doctor about these side effects before starting treatment so that you’ll understand what to expect. Depending on the condition being treated, radiation therapy can sometimes be combined with other treatments like chemotherapy or surgery for even better results.


In conclusion, the presence of swollen lymph nodes can signify a wide variety of medical conditions. Therefore, it is important to talk to your doctor if you observe any swelling in your lymph nodes. Your doctor will be able to perform tests and diagnose what is causing the swelling. Treatment options can range from simple over-the-counter medications to more involved treatments such as radiation and chemotherapy.

As with any health issue, early detection and diagnosis can lead to more successful treatment outcomes.
