Hello. So my Kayly just went through a really poor shed. After said shed, they're were two pieces that hadn't come off, one on the back and one on the tip of the tail. The one on the back came off on its own after the first day or so but the tail one stuck. I tried soaking and setting if we could get it off but that didn't work either so I figured I'd give her another day or two. I decided that I would check on her and see how it was but when I picked her up, I found this. The old skin is fine but it looks like it might be missing a scale or something. It's red like it might be bleeding a bit too. Is this an injury that needs treatment or will it heal on its own?
