If this condition is mild and it does not bother you, then you may not need treatment. But if your nail fungus is painful and it has caused thickened nails, then you can take self – care steps and medications which can help you. In many cases the treatment of the nail fungus is successful, but it often comes back. This condition is also called tinea unguium and onychomycosis. When the fungus affect the areas between your toes and the skin of your feet, then this condition is known as tinea pedis or Athlete’s foot.

Fungi can invade your skin through cuts which are so tiny and you cannot see them. Also fungi can invade your skin through a small separation between your nail and nail bed. This occurs more often in toenails than the fingernails because:

  • Toes usually have less blood flow than do fingers, making it harder for our bodies immune system to detect and stop the infection
  • Toenails often are confined in a dark, warm, moist environment, particularly inside your shoes, where fungi can thrive
