Traumatophobia
According to the DSM-IV classification of mental disorders, the injury phobia is a specific phobia of blood/injection/injury type. It is an abnormal, pathological fear of having an injury.
Another name for injury phobia is traumatophobia, from Greek τραῦμα (trauma), "wound, hurt" and φόβος (phobos), "fear". It is associated with BII (Blood-Injury-Injection) Phobia. Sufferers exhibit irrational or excessive anxiety and a desire to avoid specific feared objects and situations, to the point of avoiding potentially life-saving medical procedures. According to one study, it is most common in females and people with less education.
