Surgical wound infection - treatment


Surgery that involves a cut (incision) in the skin can lead to a wound infection after surgery. Most surgical wound infections show up within the first 30 days after surgery.

Surgical wound infections may have pus draining from them and can be red, painful or hot to touch. You might have a fever and feel sick.
