Hematoma under the nail
You are most likely to experience dark purple discoloration under the nail and pain from blood pressure trapped between the nail and the nail bed. If the pain is mild and a small part of the nail bed is discolored, you can relieve symptoms with ice, elevation of the limb, and anti-inflammatory medications. If you are in severe pain and the blood covers most of the area under the nail, the doctor will drain it through a small hole in the nail. This usually relieves the pain quickly and painlessly. The nail may fall off after a few weeks. If the subungual hematoma covers half or more of the nail, nail extraction and stitches may be needed to help a new nail grow. The nail should grow within 6 to 12 weeks. If a bone is also broken in the arm or leg during the injury, the doctor may prescribe a splint and antibiotics.
If the subungual hematoma covers more than half of the nail, it is possible that you have broken a bone.
