fester

v. be inflamed; produce pus (from a sore); cause pain; decay; eat away at; leave a scar

n. sore, inflamed wound

Gangrene is the necrosis and subsequent decay of body tissues caused by infection or thrombosis. It is usually the result of critically insufficient blood supply sometimes caused by injury and subsequent contamination with bacteria. This condition is most common in the extremities. The best treatment for gangrene is revascularization (restoration of blood flow) of the affected organ, which can reverse some of the effects of necrosis and allow healing. Depending on the extent of tissue loss and location, treatment other than revascularization may range from allowing digits to auto-amputate (fall off), debridement and local care, to amputation, the removal of infected necrotic tissues.
