This condition is Congestion.

Mostly we have lymphatic congestion; lympatic system is a drainage network of fluid, organs and vessels that is responsible for the removal of cellular debris, large proteins, foreign bodies, pathogenic agents and excess fluid from the extracellular spaces. Lymphatic congestion is a condition in which lympatic system fails to drain properly, allowing toxins and cellular waste products to accumulate in the body.
