Black and blue nails often indicate trauma or injury to the nail, causing blood to pool under it. This condition is called a subungual hematoma. It can result from dropping something heavy on the toe, stubbing it, or wearing tight shoes during physical activities. Treatment involves reducing pressure and pain by icing, elevating the injured limb, and in severe cases, seeking medical attention for drainage.
