Updated: 2025-02-06

Description

Death of cells or tissue through disease or injury.

Self-care

To prevent infection, run water over minor injuries to clean them, and remove any debris with tweezers. A thin layer of antibiotic ointment may be used for dirty wounds. Cover the injury with a sterile dressing. Once necrosis is present medical care is needed.

When to seek immediate medical care

See a healthcare professional right away for:

• Severe, persistent pain.
