Your Lymphatic System, or drainage system, consists of vessels, cells, tissues, and organs. The lymphatic vessels transport fluids and plasma proteins, passing through lymph nodes, which clean and filter the lymph fluid that is then emptied into the blood circulation at the subclavian veins. The lymphatic system protects the body by making sure the lymph nodes filter out harmful material before returning the fluid to the blood. If your lymph vessels get damaged, water retention or edema occurs in the area normally drained by them. There are hundreds of lymph nodes in the body found in clusters in your neck, armpit, groin, and behind the knee. The Reflexology Lymph Drainage technique can provide relief from symptoms of secondary lymphoedema and can help alleviate the swelling, pain, and stiffness associated with this condition.
