As promised, here are some photos of Matthew's extra 'ankles'. They do flatten out a bit when his foot is straighter, but in this position they are rather noticeable and rather hard. They are not callouses. If any one has any experience or idea, I'd love to hear it.
This picture you can see the two bumps. This was taken about an hour after he had removed his AFO. They don't seem to be where his AFO rubs.
Another view. You can see the bump closest to his ankle is big enough to be another ankle and the second one is still little. I suppose that means it is just forming?
And lastly, here is a video of Matthew walking up the stairs without his AFO. He knew I was taping him so he tried to walk straighter. And no, I have not vacuumed my stairs this week. You can see his foot does not function properly.
