Thank you, will 100% call the vet and get her in. She's gone back into her viv now and is slithering about (as I type this she is having a good drink lol) and she isn't dragging her tail/section below where the wound is so I'm taking that as a good sign.
please keep us posted. if you say she's moving normally, then yes that sounds like a good sign. just so i have a better picture: where at on the body is the wound? like that last quarter section? jc.
