Treatment of plantar warts or verrucae

Treatment is stopped for a day or two if the skin becomes tender.
Treatment for mosaic warts
Those with mosaic warts may also begin treatment with a salicylic acid of formaldehyde containing gel. If there are a large number of small verrucae the area is soaked for 10 minutes at night in a weak formaldehyde solution.
