<unk> s can resolve on their own, without treatment being necessary. If they are acutely painful, they may be drained.<unk> s are treated by either making a hole through the nail into the<unk>  (trephining) within 48 hours of injury, draining the blood and releasing the pressure, or, less conservatively, by removing the entire nail. In hospital or medical setting, trephining is generally accomplished by using an electrocautery device or an 18-gauge needle. If neither of these is available a heated (red hot) paper clip can be used to drain the blood underneath of the nail. To do this the tip of a paper clip needs to be heated till it's red hot and (the red hot) paper clip gently placed on the center of the<unk>  (center of the black area underneath of the nail). A hole will appear in the nail and the blood will drain, relieving the pressure. The hole has to be covered with sterile dressing and the nail should be kept dry afterwards. Removal of the nail is typically done when the nail itself is disrupted, a large laceration requiring suturing is suspected, or a fracture of the tip of the finger occurs. Although general anesthesia is generally not required, a digital nerve block is recommended if the nail is to be removed. For trephination, the block is often more painful than the procedure. Complication rates from both forms of treatment are low, and the nail generally recovers a normal appearance.
