Summary Manual lymph drainage (MLD) was a recognized treatment of edema well before clinical evidence of efficacy was established. But to achieve a satisfactory result, does the lymphatic outlet have to be unblocked? The answer is no, this outlet lies at the summit of the edema. Should space have to be prepared downstream? No. Generally, the edema is evacuated via a deep circuit, difficult to access with manual maneuvers. Can MLD aspirate distant edema? No. Try aspirating a gel through a straw, proof enough. Should edema always be worked downwardly? As long as the edema is reversible, working the summit has little effect, better starting from the lower areas. Should the massage roll the skin upward? Only when there is no underlying edema, but if there is, the skin should be rolled downward. Is light manual drainage always the best? No, light pressure is to be used when the edema is reversible; otherwise, the pressure should be proportional to the consistency of the edema.
