Lymphedema - Why do our limbs swell?

What is lymphedema?

Lymphedema refers to swelling that generally occurs in one of your arms or legs. Sometimes both arms or both legs swell.

Lymphedema is most commonly caused by the removal of or damage to your lymph nodes as a part of cancer treatment.

While there is presently no cure for lymphedema, it can be managed with early diagnosis and diligent care of your affected limb.

Lymphedema signs and symptoms, which occur in your affected arm or leg, include:

  • Swelling of part or all of your arm or leg, including fingers or toes
  • A feeling of heaviness or tightness
  • Restricted range of motion
