Nail Problems

You could have injured the finger or toe in a way that requires prompt evaluation. For example, if there is a dark purple, red or black area under the nail, you might have a "subungual hematoma" (meaning "blood under the nail") which can be drained to provide relief. Another possibility is that you broke a bone in your finger or dislocated it. For significant pain in the fingernail or toenail that followed a direct injury, see your physician for evaluation, especially if the pain is not improving on its own.
