Diagnostic tests will depend on what other symptoms, if any, exist. These may include x-rays, blood tests, or examination of parts of the nail in the laboratory.
Do not bite, pick, or tear at your nails (in severe cases, some people may need psychological help or encouragement to stop these behaviors).
Keep hangnails clipped.
