Swollen lymph nodes, also known as “swollen glands,” are a common health concern that many people experience at some point in their lives. They are often a sign that your body is fighting an infection or other underlying health condition. While most cases are harmless and resolve on their own, persistent or painful swelling may indicate a more serious problem that requires medical attention.
What Are Lymph Nodes and Why Do They Swell?
Lymph nodes are small, bean-shaped structures that are part of the lymphatic system. They play a vital role in your immune defense, helping to filter harmful substances like bacteria, viruses, and abnormal cells. You can find lymph nodes in various parts of your body, including your neck, underarms, groin, and behind your ears.
When lymph nodes swell, it is usually because they are working hard to fight an infection or illness. This swelling, called lymphadenopathy, is often temporary but can sometimes signal more significant health concerns.
Common Causes of Swollen Lymph Nodes
Swollen lymph nodes can be caused by a variety of factors, ranging from mild infections to serious conditions. Here are some of the most common causes:
1. Infections
Infections are the leading cause of swollen lymph nodes. These include:
- Viral infections like the common cold, flu, or mononucleosis.
- Bacterial infections such as strep throat or an infected tooth.
- Ear infections that lead to localized swelling in the neck or jaw.
- Skin infections, including cellulitis or abscesses near the lymph nodes.
- Tuberculosis (TB), a bacterial infection that can affect lymph nodes.
2. Immune System Disorders
Conditions that affect the immune system can also cause lymph node swelling. Examples include:
- Rheumatoid arthritis, a chronic inflammatory disorder.
- Lupus, an autoimmune disease where the immune system attacks healthy tissues.
3. Cancers
Swollen lymph nodes can sometimes be a symptom of cancers such as:
- Lymphoma, a cancer of the lymphatic system.
- Leukemia, a cancer of the blood and bone marrow.
- Metastatic cancer, where cancer from another part of the body spreads to the lymph nodes.
4. Medications
Certain medications, such as those for seizures or vaccines, can cause lymph node swelling as a side effect.
5. Other Causes
- HIV/AIDS, which weakens the immune system.
- Sarcoidosis, an inflammatory disease affecting multiple organs, including lymph nodes.
Symptoms to Watch For
Swollen lymph nodes are usually easy to identify. Common symptoms include:
- A noticeable lump under the skin, often in the neck, underarms, or groin.
- Tenderness or pain in the affected area.
- Redness or warmth around the swollen lymph node.
- General symptoms like fever, fatigue, or night sweats (in some cases).
If the swelling persists for more than a few weeks, feels hard or immovable, or is accompanied by unexplained weight loss or fever, it’s crucial to seek medical attention immediately.
How Are Swollen Lymph Nodes Diagnosed?
Doctors at Continental Hospitals will perform a detailed evaluation to determine the cause of swollen lymph nodes. This may include:
Physical Examination: To check the lymph nodes' size, location, and tenderness.
Blood Tests: To identify infections or immune system conditions.
Imaging Tests: Ultrasound, CT scans, or X-rays to assess the underlying cause.
Biopsy: In rare cases, a small tissue sample is taken from the lymph node for analysis.
Treatment Options for Swollen Lymph Nodes
Treatment for swollen lymph nodes depends on the underlying cause. Here are some common approaches:
1. Infections
Viral infections: These usually resolve on their own with rest, hydration, and over-the-counter medications for symptom relief.
Bacterial infections: Antibiotics are prescribed to eliminate the infection.
Skin infections: Topical or oral antibiotics may be required.
2. Immune System Disorders
For autoimmune conditions like rheumatoid arthritis or lupus, medications such as corticosteroids or immunosuppressants are used to manage inflammation.
3. Cancers
If the swelling is due to cancer, treatment options may include:
- Chemotherapy
- Radiation therapy
- Surgery to remove the affected lymph nodes
4. Home Remedies
For mild cases, you can manage discomfort at home by:
- Apply a warm compress to the swollen area.
- Taking pain relievers like ibuprofen or paracetamol.
- Staying hydrated and getting adequate rest.
When to See a Doctor
Swollen lymph nodes often resolve within a week or two, especially if caused by minor infections. However, you should consult a doctor if:
- The swelling lasts longer than two weeks.
- The nodes feel hard, fixed, or rapidly increasing in size.
- You experience unexplained weight loss, fever, or night sweats.
