This nice patient was 37 and had this foot corn since he was 15.
He'd had insoles, cream and lots of various appointments - to no avail.
He did a good job at getting the overlying hard skin flat and level which reduced the pain a little. However, this meant that the ingrowing hard corn skin underneath was compact and solid!
With these type of corn removals (ones that have been there years) I always try and remove hidden bits of corn that remain after the main plug is removed.
This is because these tend to be what causes pain even after an appointment.
(I used Gehwol Fusskraft Mint to soften the corn right at the start. I find this works away underneath and makes the years old corn skin easier to dig out)
The last stage of this corn removal is here.
