How does lymphedema form and how is it recognized?

When the lymphatic system does not work properly it has problems receiving the fluids carried by the venous system, which therefore accumulate in the space between the lower skin wall and the upper part of the muscles, causing a pressure higher than what should be there. under normal conditions.
Due to this excessive pressure there is the risk of weakening the fibers that allow the skin and muscles not to move too far. If this happens, edema will form resulting in swelling.

The swelling initially grows slowly and generally causes no pain.
