- Black Spot on a Banged Fingernail
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: Recently, while trying to accomplish some home repairs, I banged
- the nail on my finger instead of the nail in the board. Now there is an ugly
- black spot on my nail. Can this be related to the dangerous type of cancer
- which causes black spots?
-

- ANSWER: Your problem is a very common one and most amateur carpenters have
- experienced it at one time or another. The medical name for the black spot is
- "subungual hematoma." Those fancy words mean that you have a blood clot
- underneath your nail which, since the nail is transparent, appears as if it is
- in the nail. Initially, the pain must have been quite intense created by the
- pressure of the clot on the sensitive nail bed. A physician can help to
- relieve such pain by drilling a small hole in the nail and letting the
- accumulated blood seep out. That's a little late for you now and you'll just
- have to put up with the black spot until the nail grows out. The average
- fingernail grows from 0.5 to 1.2 mm per week and full regrowth of the nail
- may require from four to six months. When this injury occurs to the great
- toe, it's frequently called "tennis toe" and in that case you would have had
- to wait from twelve to eighteen months for full regrowth. Fortunately, this
- black spot has nothing to do with the skin cancer called melanoma, a very
- serious tumor which must be totally removed surgically.
