Believe it or not, but Vick’s VapoRub has become a secret weapon to treating Nail fungus! You wash the nail with soap and water, then file down the surface enough to rough it up a bit. Apply the Vicks to the nail bed overnight. Within a few weeks, you should see improvement. Always make sure to check with a doctor before starting any medication, even if it’s topical, as there may be an underlying problem at work.
