Thank you, I really hope it doesn't spread! I'm suspicious about the bone fragments too, although the bright red burning is more symptomatic of nerve damage. I'm going back next week to request more x-rays or MRI.
See some more images from today just at the office - see the purple color which I think is more consistent with soft tissue damage rather than neuropathy?
