Compression. Lymphedema is cause impaired circulation of lymph. Normally the compression of muscles propels the lymph through lymphatic system, however if the is obstruction it need extra help. That can from compression stockings, lymphatic massage, or compression boots or pumps that inflate. All of these things give an extra boost to lymph circulation.
Lymphedema treatment. As drs. Wright and bein said, the treatment is manual lymphatic drainage, compression stockings, decongestion exercises, weight loss (if needed), and intermittent pneumatic compression. Sometimes inelastic compression works better and is easier to use than compression stockings (see www.Circaid.Com). It is important to see a lymphedema therapist for treatment, education, and other recommendations.
