3 month back one day I recognize that very small hard skin or like soft stone at my left leg feet just near hell. but from last mid of august if feel pain while walking. Before that it was only a hard skin or some kind of circular tight skin pained at the centre only when pushed or touched hardly by something. So, I consult with friends and use a corn cap for six days. As it still not removed I used a lotion called DUOFILM as per product's instruction from last 4-5 days. Pain got reduced but still problem(light pain) is there. Also it seems to be little larger in size and make large flat area of yellow colour compare to earlier. Please suggest whether continue with the lotion or I should do something else.
