The short version of today's app't with the surgeon:
We came up with a plausible reason why the wound temporarily deteriorated when it did. (Notice I said "temporarily". Yes, it started improving again the next day.
) Either it will heal completely, in its own good time and without any further treatment, or it will need extensive surgery. He doesn't recommend considering surgery for at least three months. So, next appointment in three months, but holler if I need him in-between.
Wave bye-bye to this thread, folks.
