This lovely patient had pain from this corn under her pinky-toe since a surgery a few years ago.
Hard skin had built up first (under a tailor's bunion), then a corn.
Removing this corn was about getting rid of the valleys first; then really picking out the very bottom with a gouge blade. (This is actually the second part of this corn removal video).
This was quite a small foot corn in terms of diameter — but pretty deep to the bottom.
Ideally, I'd like to offload the area going forward to ensure the pressure that creates this foot corn stays off it.
(If you think you have one of these, be sure to apply plenty of Gehwol Fusskraft Mint to stop it growing down)
