10 Gangrene Symptoms
2. Swelling
One important sign of gangrene is the swelling or edema that surrounds the affected body part. For example, it is one of the initial signs of wet gangrene. Additionally, it may be associated with redness, warmth, and the formation of oozing blisters on the surface of the skin. Furthermore, a rare type of gangrene known as gas gangrene, can also produce massive swelling in the affected region. It is caused by a genus of gas-forming bacteria known as Clostridium. Gas gangrene is a medical emergency because it spreads quickly and it is highly fatal.
Another rare type of gangrene is Fournier’s gangrene (FG). It is a type of necrotizing fasciitis, which means that it entails the death of certain tissue under the skin, that results of a bacterial infection (i.e. streptococcus pyogenes). FG commonly affects the genital and perineal area, especially in males with diabetes; although it can also affect children and women. The initial signs and symptoms of FG include severe pain and local swelling in the affected area.
