The pain is described as being more severe than would be expected from the appearance of the wound. Late symptoms can include death (gangrene) of affected areas with scaling, discoloration, or peeling of the skin.
Many of the people who have developed necrotizing fasciitis have been in good health before developing the condition. People with chronic medical conditions (for example diabetes and cancer) or who have weakened immune systems are at an increased risk of developing necrotizing fasciitis. Recent wounds (including surgical incisions) and recent viral infections that cause a rash (such as chickenpox) also confer an increased risk.
Necrotizing fasciitis is treated with antibiotics, and early treatment is critical. Hospitalization, usually with treatment in the intensive-care unit (ICU), is required. Surgery to remove infected fluids and tissue may be necessary, along with medications to treat shock and other potential.
