The skin varies in thickness from .5 mm on your eyelids to 4 mm thick on the heels of your feet. That’s not very thick, as there are 25.4 mm to an inch, and that’s only on the heels of your feet.
I just showed this to a nurse. In her opinion, it should be stitched, treated, and bandaged.
I don’t know who this is, but it should not be taken lightly or go unseen by a trained, medical professional.
It looks like the skin is separated from being cut, but not missing. Stitches would pull it back together and close it up, which would help to prevent infection.
You can see this cut is placed where a previous cut was, along with other previous cuts in the area. They really will not stitch wounds open more than 24 hrs to prevent stitching in infection. With the healed cuts on her legs and all I would say this girl has indeed got problems.
That’s certainly a possibility, but even so, the edges could be pulled back together with stitches, or maybe another method.
That’s a fair point. I checked with a different nurse who said it looked like it could be stitched, and confirmed your point about not stitching in infection.
