Hello..Thanks for your query
It is important to get your self checked by a dermatologist
in this case.This would help you to confirm if you are having callus
or plantar warts
.In either case , the removal method is surgical removal of the extra thickened area in the soles.Medical methods do not work very well here and also it takes lot of time to reduce the thickness of the callosities.
Hence i would advise a dermatologist visit soon; if you have plantar warts , they may potentially spread to the surrounding areas .
Hope this is helpful
