- Tight footwear promotes crowding of the toes keeps the toes warm and moist
- Diminished blood circulation
- More years of exposure to fungi
- Perspiring heavily
- Working in a humid or moist environment
- Having the skin condition psoriasis
- Wearing socks and shoes that hinder ventilation and don’t absorb perspiration
- Having athlete’s foot (tinea pedis)
- Having a minor skin or nail injury, a damaged nail, or another infection
- Exercise can cause repeated minor trauma to the hyponychium allowing fungi to invade
- Communal showers can expose the feet to fungi

CLINICAL MANIFESTATIONS
- Usually, there are no symptoms. It is often a cosmetic problem
- Occasionally, it can cause pain or discomfort
- The nail usually a brittle, thickened, dull, and easily breakable
- Debris accumulates under nail plate and nail plate separates
- Sometimes, surrounding skin can become infected and cause cellulitis (inflammation)

MANAGEMENT
Onychomycosis is difficult to treat because one has to take medicines for a very long time, and often the problem comes back after stopping the medication
- Oral medications: to treat nail fungus, doctor may prescribe an oral antifungal medication. Studies have shown the most effective treatments to be terbinafine and itraconazole (sporanox).
- Antifungal Lacquer: if you have a mild to moderate infection of nail fungus, doctor may prefer to prescribe an antifungal nail polish called ciclopirox (penlac)
- Topical medications: doctor may also opt for other topical antifungal medications. Advised to use these creams with an over-the-counter lotion containing urea to help speed up absorption
- Surgery: if nail infection is severe or extremely painful, doctor may suggest removing nail. A new nail will usually grow in its place, though it will come in slowly and may take as long as a year to grow back completely.
