What is lymphoedema?

is in all body tissues. It comes from the tiny blood vessels into the body tissues. Normally it drains back into the bloodstream through channels called lymph vessels. These are part of the lymphatic system.

Blocked, removed or damaged lymph drainage channels or lymph nodes cause a build up of lymph fluid. This is the swelling called lymphoedema.

Symptoms of lymphoedema

The main symptom you might notice is swelling in part of the body. This may come and go. Your clothes, shoes, watch or jewellery may become tighter. Or you might have marks or dents where clothes dig into the skin.

The swelling may be soft and easy to push in with your fingers, leaving a dent. This is called pitting oedema. The swelling may also be non-pitting.

Other symptoms in the area affected can include:

  • a feeling of heaviness or fullness

  • your skin feeling tight and thicker. It might also be dry, cracked and less stretchy

  • aching

  • difficulty moving

  • tingling feeling

There are other reasons why people develop swelling. But if you notice any swelling that doesn’t go away, contact your doctor.
