Fungus is a natural part of the skin. It is always present in certain amounts. This is why it can be difficult to know how or why you have developed a toenail fungus. While it can appear to occur for no apparent reason, there are many variables that do contribute to this infection.
Toenail fungus is a common problem because it is extremely contagious. It is considered harmful due to the fact that it leads to discoloration and disfigurement of the toe; the two toes most commonly affected are the big and little toes.
Toenails can easily crack and rupture because of the amount of wear and tear they sustain. Because a fungus likes warm, wet areas to reside in, these cracks in the nail make a perfect breeding ground for fungus.
Public areas such as public gyms and swimming pools are areas where moisture and dampness are prevalent, allowing for fungus to spread to your feet.
Shoes and Socks
Wearing tight-fitting shoes and socks after exercise traps in moisture, allowing for the fungus to embed itself under the cracks of the nail.
Medical conditions such as diabetes and poor circulation also contribute to toenail fungus.
Some symptoms to watch for include a yellow or brown discoloration of the nail, a smelly debris under the affected nail, a nail that has become thick or nails that begin falling off.
