A black toe tells us there is blood-filled swelling (subungal hematoma) under the nail. The blood under the nail turns dark and black. There is usually pain and tenderness in the toe. This is a traumatic injury, either a one-time event or several repetitive events. It occurs with the toe or toes repetitively bumping against the front of the shoe and is found in those who recreationally run or play other high impact sports. Those with Morton’s Toe (a long second toe and a shorter big toe) are especially susceptible if they engage in running or other repetitive recreational activities.
It takes about 12-18 months for the nail to fully grow back due to poorer blood circulation in that part of the body. It may also grow back misshapen.
Other names or similar foot conditions:
- Toe hematoma
- Blood under the toenail
Symptoms:
- Toenail turns black after injury or repetitive foot activities
- Pain in the toe with direct pressure on it
Signs to look for:
- Black toenail
- Shoes worn at toe box or end of shoe
- Running or other recreational activities where there is repetitive bumping of toes against the front of the shoe
Possible Causes:
- Traumatic injury to toe and/or repetitive bumping of toes against shoe
- Wearing shoes that are too narrow or short
Goals:
- Modify how toes hit the ground so there is less pressure on the nails
- Footwear that gives more room to the toes
- Protection of the toenails when engaging in recreational activities
- Protection of the new and old toenail from fungal infection
How We Help:
Arch Supports:
- BioOrthotics exercising support with metatarsal lift
- Lower and thinner arch support with longitudinal and metatarsal support for use when shoes cannot accommodate the BioOrthotics exercising support
Shoes:
- Extra depth, double or triple depth shoe with high toe box, firm heel counter, rocker sole and connecting shank
- Correct length and width of shoe and personal stride component for the foot and the activity required
Other:
- If repetitive recreational activities are the cause, along with the above arch support and shoe corrections, place moleskin cut to the size of the affected toenails for use during the activity
- Cooper, bamboo or silver socks that have anti-bacterial properties and wick moisture away from the skin
- Use anti-fungal cream and nail restorer oil on the toe regularly until the nail completely grows back
