I’ve had this on my foot for years now. Like 5 years. I shave it down and it grows back, once the callous grows back it starts to hurt when the callous gets too big so I shave it down again then that provides relief. I have been to the doctor she is unsure what it is and has tried to treat it with cold laser whatever they use for warts but it continues doing this callous regrown. What is this and how do I finally fix this!
Photos are of the thick skin that grows over this white area. I peel that thick skin off after I shave it down.
