How do I know if I have Lymphoedema?

Lymphoedema is a chronic condition characterized by the abnormal accumulation of lymphatic fluid in the body's tissues, typically resulting in persistent swelling, often in the arms or legs. If you notice localized swelling that does not resolve with elevation, feels heavy, or results in skin changes, it is important to seek a clinical evaluation to distinguish Lymphoedema from other causes of edema.

What are the early signs and symptoms of Lymphoedema?

The hallmark of Lymphoedema is swelling that often begins subtly. Early indicators include a feeling of heaviness or tightness in a limb, clothing or jewelry feeling tighter than usual, and skin that feels firmer or thicker. Unlike common fluid retention, Lymphoedema swelling often starts distally (in the fingers or toes) and progresses upward. You may notice "pitting" edema, where pressing a finger into the skin leaves an indentation, though in later stages, the skin may become non-pitting and fibrotic.

How can I perform a self-assessment for Lymphoedema?

To monitor for Lymphoedema, observe your limbs for asymmetry. Look for these specific patterns:

• Persistent swelling that does not improve significantly with limb elevation or overnight rest.


• A "square" appearance of the toes or fingers (Stemmer’s sign, where you cannot pinch the skin at the base of the second toe or middle finger).


• Recurring skin infections (cellulitis) in the affected area.


• Changes in skin texture, such as dryness, hardening, or the development of wart-like growths.

When should I see a doctor and what tests are used?

If you suspect you have Lymphoedema, consult a primary care physician or a lymphology specialist. Describe the duration of the swelling and any history of surgery, radiation, or trauma. Diagnostic tests often include a physical examination, and in complex cases, lymphoscintigraphy or indocyanine green (ICG) lymphography may be used to visualize the lymphatic drainage. Do not be afraid to advocate for yourself; if your concerns are dismissed, request a referral to a certified lymphedema therapist (CLT) who can perform a specialized physical assessment.

What are the red flags requiring urgent care?

Seek immediate medical attention if you experience sudden, rapid onset of swelling accompanied by high fever, chills, or red, hot, painful skin, as these are clinical signs of cellulitis, a common and potentially serious complication of Lymphoedema.

Next steps

• Schedule an appointment with a physician to document your symptoms.


• Keep a daily log of limb measurements and note any triggers for increased swelling.
