Caused by the Human Papilloma Virus (HPV). A true wart requires implantation of the virus into your skin. The most common methods are splinters, thorns, shards of glass, and even running barefoot around pools. They can be difficult to completely get rid of, especially once the virus replicates to cause more warts known as satellite lesions.
Fungal infection of the skin usually characterized by burning, itching, and peeling skin. It can be present only on one foot. Prescription grade anti-fungal medications are indicated if over-the-counter medications have shown little to no relief.
Fungal infection of the nails. Treatment often takes several months. Trauma can cause a damaged nail root which then causes the nail to thicken and deform and it often mistaken as a fungal nail.
