A cut (laceration) occurs when the skin is sliced below the surface. A puncture wound is a deep cut that occurs when a sharp object penetrates the skin. A cut can require home treatment or the need for professional care, depending on the location and severity of the wound.
The skin around the ulcer may be red, swollen, and tender. Patients may feel pain on the skin around the ulcer, and fluid may ooze from the ulcer. In some cases, ulcers can bleed and, rarely, patients experience fever. Ulcers sometimes seem not to heal; healing, if it does occur, tends to be slow.
