(This is a longer version of the previous video)
Effectively this was two foot corns; the oval-shaped one here and a smaller one underneath that!
To get anywhere near the corn here, I had to gently par away the thick overlying callus.
This patient only has this foot corn. It had formed up over years from a severe bunion throwing off her walk on that side.
She'll need a nice comfy insole and plenty of good callus cream to keep it under control.
