Nail fungus can look unsightly and may cause embarrassment. Typically, the nail becomes thicker and changes to a yellowish-brown. The infection can spread to the surrounding nails and even the skin. It can also be contagious, spreading from one nail to another, and from one person to the other. Therefore, it is important to treat nail fungus as soon as symptoms arise and the infection has been diagnosed.
