Understanding Swollen and Tender Lymph Nodes
Swollen lymph nodes are a common sign that your immune system is responding to an infection, inflammation, or another underlying medical condition. While enlarged lymph nodes often improve as the underlying illness resolves, persistent swelling, significant tenderness, or other concerning symptoms should be evaluated by a healthcare provider.
This guide explains the role of the lymphatic system, common causes of swollen lymph nodes, available treatment options, and how our Relatyv Neurofunctional Pain Management approach may complement your overall care plan when chronic pain is contributing to your symptoms.
What Are Lymph Nodes?
Lymph nodes are small, bean-shaped structures located throughout the body, including the neck, armpits, chest, abdomen, and groin. They are part of the lymphatic system, a network of vessels and organs that helps maintain fluid balance and supports the immune system.
Lymph nodes act as filters, trapping bacteria, viruses, abnormal cells, and other potentially harmful substances. They also contain immune cells that help your body recognize and respond to infections.
Why Do Lymph Nodes Become Swollen?
Lymph nodes often enlarge because they are actively responding to an infection or another immune system trigger. Common causes include:
Infections
Viral, bacterial, or fungal infections are the most common cause of swollen lymph nodes. Common examples include colds, influenza, strep throat, mononucleosis, skin infections, and dental infections.
Inflammatory Conditions
Inflammation caused by autoimmune diseases or other chronic medical conditions can also result in enlarged lymph nodes.
Allergic Reactions
Some allergic reactions may stimulate the immune system and contribute to temporary lymph node enlargement.
Certain Medications
Although uncommon, some medications may cause lymph node swelling as a side effect.
Cancer
Less commonly, swollen lymph nodes may be associated with cancers such as lymphoma, leukemia, or cancers that have spread to nearby lymph nodes. Persistent or unexplained enlargement should always be evaluated.
Symptoms That May Occur Alongside Swollen Lymph Nodes
Depending on the underlying cause, swollen lymph nodes may occur with:
- Tenderness or pain.
- Fever.
- Sore throat.
- Cough.
- Fatigue.
- Night sweats.
- Chills.
- Skin redness or warmth near the affected area.
Medical Conditions Associated with Swollen Lymph Nodes
Rheumatoid Arthritis
This autoimmune condition can cause chronic inflammation that occasionally results in enlarged lymph nodes.
Lupus
Systemic lupus erythematosus may cause swollen lymph nodes along with joint pain, fatigue, skin rashes, and other symptoms.
Sjögren’s Syndrome
This autoimmune disease primarily affects moisture-producing glands but may also cause lymph node enlargement.
Crohn’s Disease
Inflammatory bowel diseases such as Crohn’s disease may be associated with enlarged lymph nodes due to ongoing inflammation.
Chronic Fatigue Syndrome
Some people with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) report tender lymph nodes along with persistent fatigue and muscle pain.
When Should You Seek Medical Care?
You should schedule a medical evaluation if swollen lymph nodes:
- Persist for more than two to four weeks.
- Continue to increase in size.
- Become increasingly painful.
- Occur without an obvious illness.
- Return repeatedly.
Seek prompt medical attention if swollen lymph nodes are accompanied by persistent fever, difficulty swallowing or breathing, unexplained weight loss, drenching night sweats, significant redness or drainage, or rapidly enlarging lymph nodes.
How Swollen Lymph Nodes Are Diagnosed
Your healthcare provider may recommend:
- Medical history review.
- Physical examination.
- Blood tests.
- Ultrasound, CT scan, or other imaging studies.
- Testing for infections or autoimmune diseases.
- Lymph node biopsy when necessary to determine the underlying cause.
Conventional Treatment Options
Treatment depends on the underlying cause of the enlarged lymph nodes.
Medications
Your healthcare provider may prescribe antibiotics for bacterial infections, antiviral medications when appropriate, anti-inflammatory medications, or treatments for autoimmune diseases depending on the diagnosis.
Physical Therapy
When swollen lymph nodes are associated with musculoskeletal or autoimmune conditions, physical therapy may help improve mobility and reduce discomfort.
Injections
For certain inflammatory conditions, corticosteroid injections may be appropriate to help reduce inflammation under the guidance of your healthcare provider.
Surgery
Surgical procedures are rarely required for swollen lymph nodes but may be recommended to drain an abscess, remove a suspicious lymph node for biopsy, or treat certain cancers.
Our Relatyv Neurofunctional Pain Management Approach
At Relatyv, our Neurofunctional Pain Management approach is designed to help manage chronic pain associated with neurological and musculoskeletal conditions. Our care complements appropriate medical evaluation and treatment rather than replacing it.
Each treatment plan is individualized based on your diagnosis, symptoms, and goals. Care may include electroanalgesia, IV therapy when clinically appropriate, nutritional support, and lifestyle recommendations that complement your existing medical care.
While treatment may help reduce pain and improve function for some individuals, outcomes vary depending on the underlying cause of the condition.
Supporting a Healthy Immune System
You may be able to support your immune system and overall health by:
- Getting adequate sleep.
- Eating a balanced, nutrient-rich diet.
- Staying physically active.
- Practicing good oral hygiene.
- Managing chronic medical conditions.
- Seeking prompt treatment for infections.
Find Relief from Chronic Pain
Swollen lymph nodes are often a temporary response to infection or inflammation, but persistent or unexplained enlargement should always be evaluated by a healthcare provider. An accurate diagnosis is essential for identifying the underlying cause and determining the most appropriate treatment.
At Relatyv, we provide personalized, non-invasive care designed to help reduce chronic pain and improve function. Our Neurofunctional Pain Management approach may complement your existing medical treatment while supporting improved comfort, mobility, and quality of life.
