My gecko just shed and recently shes been getting skin stuck under her tail and vent area so I was helping pick it off when I noticed she had a sort of swollen bump on her vent? her stools aren't bloody she just recently pooped and it looked fine but I'm worried as to what and why it is there and if she need to see a vet. Does anyone know what this could be from? (also I'm sorry the picture is blurry it was the best I could get cause she was a little squirmy)
