I have performed surgery on injuries that you have described. One of the challenges is to get the 'sole' to stay put once it has been sutured into place. Heavy rest and close, prolonged post op time is required. I have have to refer more than one to a surgical specialist. I would keep the site clean and obtain a surgical consulation.
