Black toenails are generally the result of blood accumulating underneath the toenail where a bruise or a blister has developed.  The amount of blood may cause the toenail to lift up, and draining may be necessary to relieve pressure.  Walkers and runners can get a black toenail when there is an injury to the toenail bed.  This can result from shoes that allow the foot to slip forward in the shoe, causing the toes to hit the toebox.  It is important to understand that a black toenail could also be due to the development of melanoma, a type of skin cancer, under the nail.  Should you experience toenail blackness that does not improve, have it evaluated by your podiatrist.
There are many problems that can affect toenails, including black nails, ingrown nails, fungal nails, and thickened nails, and a professional diagnosis is imperative in order to begin the correct treatment plan.  A complete evaluation awaits you at our office no matter what your foot concerns.  We’ll also tell you ways to prevent future nail problems from occurring.  For an appointment at 299 Lincoln Street, Suite 202, Worcester, please call 508-757-4003.
HINT:  The best way to prevent getting a black toenail is to wear shoes that don’t give too much or too little room.
