BLUE TONGUE SKINKS

So I have a skink called cloudy sky and she is doing some weird behaviour whenever I take him onto my carpet outside. Part of her tail seems to lift up slowly and she walks around with it lifted, until she somehow curls up and looks over the lifted tail or under it. I'll post a photo. Is this carpet burn or something? She doesn't poop at all after this.
Ps. The first pic is the wrong way sorry
