Other signs of wound infection include: • Delayed healing not previously anticipated. • Discolouration of tissues both within and at the wound margins. • Abnormal smell coming from wound site. • Friable, bleeding granulation tissue despite appropriate care and management. • Lymphangitis, a red line originating from the wound and leading to swollen tender lymph glands draining the affected area.
