Other risk factors include perspiring heavily, being in a humid or moist environment, psoriasis, wearing socks and shoes that hinder ventilation and do not absorb perspiration, going barefoot in damp public places such as swimming pools, gyms and shower rooms, having athlete's foot (tinea pedis), minor skin or nail injury, damaged nail, or other infection, and having diabetes, circulation problems, which may also lead to lower peripheral temperatures on hands and feet, or a weakened immune system.
For this treatment, the affected toe or finger first has to be soaked in warm water for ten minutes and then dried. After that, the urea-based cream is applied to the nail, and the nail is covered with an adhesive bandage. After 24 hours, the bandage is removed and the toe or finger is held in warm water again. The softened layer of the nail is then scraped off using a spatula, the cream is applied again and the nail is covered with a new bandage. This treatment is carried out over 14 days. Once the infected part of the nail has been scraped away completely, the skin beneath is treated for another four weeks with a bifonazole cream.
Infected nails are usually thicker than normal and could be warped or oddly shaped. They can break easily. Nails with fungus might look yellow. Sometimes a white dot shows up on the nail and then gets bigger. When fungus builds up under your nail, it can loosen and even separate the nail from the bed. The fungus can also spread to the skin around your nail.
