Female BP seems sick

Ive had this girl fot about a month now and the last couple days it seems like from (tail+6in) she is not using. Like when i open its always really stiff and even when i pick her up its like all tensed up, just in like the bottom 8in of her body.

Sounds like she could be constipated. I would soak her in 1/4 -1/2 inch of luke warm water for about 5 minuets or so and see if that help's if not go to a vet.

well she pooped like two days ago, and when i say poop i meaan a big poo.

How old is she ?

let us get some pics if you can plz
