Injured cat

Our cat has injured her front paw. It’s about twice the size of the other one, and she’s hopping around holding it off the ground, and licking it very gingerly (when she’s not sleeping, which she’s understandably doing quite a lot at the moment). We’re hoping it’s just sprained rather than broken, because it would stress the poor beast even more to take her to the vet. Is there any way of telling, that won’t hurt her too much?
