The lymphatic system plays a key role in the body’s immune defenses.
Lymphatic fluid flows through lymph vessels, which connect lymph nodes. As it passes through the lymph nodes, white blood cells trap and destroy harmful particles, such as bacteria.
Like blood in the circulatory system, lymphatic fluid is always moving. If it stops, swelling can occur, as lymph fluid builds up, often in the arms or legs. Health experts call this lymphedema.
Lymphatic massage usually forms part of a treatment program health experts call decongestive lymphatic therapy (DLT).
DLT for lymphedema includes:
- lymphatic drainage massage
- compression garments
- exercise
- skin care
Together, these can improve circulation throughout the lymphatic system and symptoms of lymphedema, including:
- swelling in the extremities — such as the arms, legs, hands, or feet — which can affect mobility
- swelling in other parts of the body, including the chest, breast, shoulder, face, and groin
- pain and changes in sensation
- a feeling of heaviness
- difficulty fitting into clothing
