If your toenail turns black, it’s most likely a bruise under the nail, technically called a subungual hematoma. You can get it from stubbing a toe or from footwear that cram your feet into the front of the shoe.
Also, how do I stop my toenails from bruising?
Keeping your toenails trimmed short and square (not curved) will also help evenly distribute stress on your toe. If you’ve already got a blackened and bruised toenail, you can leave it alone if it isn’t bothering your running. If it is, you can try soaking in warm water to relieve some of the irritation.
One may also ask, does a bruised toenail go away? A minor subungual hematoma usually heals over time without treatment. The trapped blood will eventually be reabsorbed, and the dark mark will disappear. This can take 2–3 months for a fingernail, and up to 9 months for a toenail.
Hereof, what causes bruising under toenails?
Subungual hematoma is the medical term for bleeding and bruising under the nail. This is usually the result of some kind of injury to the blood vessels under the nail bed. When space is tight in the front of a shoe, there is undue pressure on the blood vessels in the toes.
How long does it take for a bruised toenail to go away?
Recovery. Unless the area of bleeding is very small, an affected nail will usually fall off on its own after several weeks because the pooled blood has separated it from its bed. A new fingernail can regrow in as little as 8 weeks. A new toenail may not fully regrow for about 6 months.
