Toenail fungus (onychomycosis) is a very common problem and it can be hard to treat. It looks unsightly, smells unpleasant, makes walking painful, and if left untreated can cause a great deal of damage to the affected toenails. In severe cases the nails will crumble and even detach from the nail bed and fall off.
Nail fungus can lead to more serious problems too. The compromised nail provides an entry point for bacteria which can lead to serious infections like cellulitis.
Conventional over-the-counter treatments are notoriously unreliable, and prescription medications often cause side effects. And neither option offers a cost effective solution to the problem, with treatments lasting many months.
