I've had it for months and always just thought it was a callous or something. It's recently seemed to grow really quickly and today has been painful to walk on.
It looks like a verruca to me, but it sticks up and out and is hard like a corn, but I've never had a corn so I don't really know.
I'm abroad and finding a podiatrist that has good English is difficult, so wanted opinions on whether it's a home remedy job or not!
And also I'm sorry for the picture of my gross feet.
