Causes Of Black Toenail Fungus
Black toenails are not just ugly but are also often painful. It is one of the most common toenail problems especially amidst athletes who primarily engage their feet during sporting activities. Black toenails can be caused by several factors, some of which may clear up on their own. Others require treatments ranging from easy to difficult. Black toenails are caused by factors including repetitive trauma, blunt force, melanoma, pigmentation changes, underlying health conditions (e.g. diabetes, kidney disease, and heart disease), and fungus infection.
