The fluid in the lymphatic system helps remove waste and toxins from the bodily tissues. Some health conditions can cause lymph fluid to build up. Lymphatic drainage massages can benefit people with fibromyalgia, and other conditions.
Health conditions can interrupt the normal flow of lymph, causing lymph fluid to build up in a particular area of the body, often in the arms or legs, where it can causing swelling. This condition is called lymphedema.
