Black Toenails

Black toenails, also known as “blackened toenails” or “subungual hematoma,” are a common foot issue that can happen to anyone. While they might look alarming, most cases are not a cause for immediate concern. At Advanced Foot & Ankle Centers of Illinois, we’re here to help you understand the causes, how to prevent them, and when to seek treatment.

What Are Black Toenails, and What Causes Them?

Black toenails occur when the nail darkens due to a variety of reasons, ranging from minor injuries to more serious conditions. Here are the most common causes:

1. Trauma

One of the most frequent causes of black toenails is physical trauma. This can happen from repetitive stress, like long-distance running, or sudden injuries, such as stubbing your toe. The impact can rupture small blood vessels under the nail, causing blood to collect and create a black or purplish appearance.

2. Ill-Fitting Footwear

Shoes that are too tight or have a narrow toe box can press against your toenails, leading to blackening over time. High heels can worsen the issue by forcing your toes into the front of the shoe. Make sure your footwear fits properly to avoid unnecessary pressure.

3. Fungal Infections

Fungal infections, like onychomycosis, can also cause nail discoloration. Although this is less common, it’s essential to maintain good foot hygiene to reduce the risk.

4. Subungual Melanoma

In rare cases, a black toenail can indicate a more serious condition, such as subungual melanoma, a type of skin cancer. If the discoloration appears without any known trauma, changes rapidly, or has irregular edges, contact us immediately for an evaluation.

How to Prevent Black Toenails

Preventing black toenails starts with protecting your feet from injury and maintaining overall nail health. Here are some practical tips:

Choose the Right Footwear

  • Invest in properly fitting shoes with a wide toe box to allow your toes to move naturally without pressure.
  • Opt for shoes designed for specific activities, such as running or hiking, to provide the appropriate support.

Trim Your Toenails Correctly

  • Keep your toenails neatly trimmed but avoid cutting them too short.
  • Trim straight across to prevent ingrown toenails, which can lead to trauma and discoloration.

Practice Good Foot Hygiene

  • Wash your feet daily and dry them thoroughly, including the spaces between your toes.
  • Use antifungal powders or sprays if you’re prone to sweaty feet.

Protect Your Feet During Activities

  • If you’re a runner or athlete, consider wearing protective gear like toe caps or taping your toes to minimize impact.
  • Ensure your athletic shoes are well-cushioned and suitable for your foot type.

Treatment Options for Black Toenails

If you’ve developed a black toenail, proper care is essential to promote healing and prevent complications. Here’s what you can do:

Rest and Elevation

  • Avoid activities that could further injure your toenail. Rest allows the nail to heal naturally.
  • Elevate your foot to reduce swelling and improve blood flow.

Over-the-Counter Pain Relief

  • If the black toenail is painful, consider taking non-prescription pain relievers like ibuprofen or acetaminophen. Follow the dosage instructions carefully.

Consult Our Team
