Does anyone know about any lymphatic diseases; and how do you get them?

Tissue swelling. Latin lympha "water goddess" - lymph is essentially recycled blood plasma. The lymphatic system returns the interstitial fluid to the thoracic duct and then to the bloodstream, where it is recirculated back to the tissues.Tissues with lymphedema are at risk of infection and ulcer. Yes I am certified in lymphatic therapy. We use fda approved lymphedema laser therapy for lymph drainage.
