what is a toenail injury?
Trauma to the nail matrix can cause in an array of possible changes to the nail itself. Injury to the toenail can be repetitive and chronic such as friction caused by rubbing against a shoe when the person runs or walks. The injury can also be acute such as receiving an impact from a dropped item or the act of stubbing the toe. The nail matrix can bruise or bleed because of these traumas and the toenail can become thick or even fall off. If any part of the toenail has come loose, it can cause the person to develop a fungal or bacterial infection. If the impact was especially great, it can fracture the toe bone.
