The most common cause of black toenails among runners is bruising (bleeding) under the nail. Repetitive trauma of the shoe bumping the toenail can also cause the nail to thicken.
If the nail became suddenly painful, a podiatrist may need to puncture the nail to release the blood and ease the pressure. This is often the result of trauma, such as being stepped on or dropping a heavy object on the toe.
A fungal infection can discolor and thicken toenails. Treatment options include oral and topical medication. The two newest topical prescription medications are Jublia and Kerydin. Testing the nail can often identify the causative organism.
Most concerning, a black spot under or in a nail that does not go away can be a melanoma (skin cancer). Please have a podiatrist check it. A biopsy may be needed. The famous reggae singer and musician Bob Marley died from melanoma that started in a toenail.
At Skokie Foot and Ankle Specialists we provide attentive care and are trained to perform these tests, usually in our office. If you have any concerns regarding the appearance of your nails, we urge you to call us at (847) 675-3400 or click here for an appointment.
Nail polish can cause discoloration.
Some colors (pigments) can penetrate the nail, especially darker polishes. Also, “nail hardeners” such as formalin and dimethyl urea can cause yellowing when it reacts with the keratin protein in your nails.
A base coat may help. The primary reason to apply a clear base coat first is to form an even surface for applying the color polish. It may also serve as a barrier to reduce the likelihood of nail discoloration.
So what should a person do? Let your nails “breathe” for a few weeks without polish. This may help them return to a normal hue.
Take heed. Sometimes injury or fungus that was covered becomes apparent when the polish is removed.
If you are concerned about the health of your toenails, please schedule an appointment with Dr. Miller by calling (847) 675-3400 or CLICKING HERE.
ATHLETE'S FOOT is a common fungal infection of the skin that can cause peeling and itching.
Does laundering clothes eliminate the fungus?
Researches tested socks worn by patients suffering from athlete’s foot after the socks were washed in either warm or hot water (104° and 140°F, respectively). The results, published in the International Journal of Dermatology, demonstrated that:
- Dermatophytes, the most common cause of athlete’s foot, were eradicated in hot water but not warm water.
- Yeasts, a less common cause of athlete’s foot, were eradicated even when using warm water.
- Some Aspergillus survived even in hot water.
In summary, laundering at lower temperatures is NOT as effective in eradicating fungal pathogens. You can check the water temperature with a cooking thermometer.
The effect of dryer temperature remains unanswered, as the socks tested were dried at room temperature.
