Plantar warts are small growths that usually occur on the heels or other supporting areas of your feet. This pressure can also cause the formation of plantar warts under a thick, hard skin layer (callus). Plantar warts are caused by HPV. The virus enters your body through small cuts, fractures, or other weaknesses in the lower part of your feet. Most plantar warts are not a serious health problem and usually go away without treatment. You can try self-treated treatments or consult your wart remover.
While in most cases, the warts resolve naturally, it is essential to give proper treatment to the painful ones. The incubation timeframe or the time gap between the infection and the symptom appearance is estimated to be from maybe a few months to multiple years.
