Manual lymphatic drainage is a hands-on technique that helps optimize lymphatic fluid return to the lymph nodes. The job of the lymph nodes are to filter out the body’s waste products such as water, protein, white blood cells, and bacteria. When the lymph nodes are damaged due to surgery, radiation therapy, scar tissue, or from repeated injuries — there will be an accumulation of lymphatic fluid that thickens and results in edema, fibrosis (hardening of tissue) and pain. If left untreated, weeping, wounds and infections can occur. Lymphatic drainage helps improve your immune system. It helps the body absorb swelling after a surgery, and helps reroute lymph fluid after lymph node removal from cancer surgery. It can also help with bloating when you have IBS, Crohn’s disease, and premenstrual pain syndrome.
