Cellulitis occurs when skin infection affects underlying tissue. Dog and cat bites, other skin puncture wounds and deep scratches or lacerations all causes of cellulitis. The affected skin is hotter and redder than normal. Left untreated, cellulitis often breaks through the skin causing a deep, rough ulcer. If cellulitis has already ulcerated we will provide you with a dilute antiseptic solution for twice daily flushing of the wound. If it has not ulcerated, antibiotics and pain killers are used. The affected area is soaked several times daily with warm salt water to bring any underlying abscess or boil to a head. The region is lanced when a soft, fluid swelling nears the surface of the skin.
