Possible broken or sprained leg

I'm not posting this for either of my boys, this is on behalf of my neighbor as she doesn't have the interwebz.

She has two female lionheads, about 10-11 weeks old. They're from another neighbour who accidentally had a litter of four, so they are defiantly from the same litter and according to the vet they are both defiantly female. I have also checked the sex and I agree, both look female.

They don't fight although Nugget is definatly more dominant than Imp.
Imp also has a habbit of jumping from great heights if she gets nervous (She has however calmed down unbelievably since the start of last week when they got them).

So the problem is this:
Mel (my neighbor) came home from work today and noticed Imp was limping rather badly. She brought her over and I had a look as best I could. There is a little bit of swelling but nothing too noticeable. There is also no blood or wound so it doesn't look like a bite.
Mel's partner Craig had been watching them all day and he said that they hadn't fought at all and Imp defiantly hadn't fallen or jumped from any height so we're not sure what's happened to her.

Imp did jump last night but only started limping this evening, could it have taken till now to be causing her pain?
We will be taking her to the vets first thing tomorrow but I was wondering if anyone had any thoughts on what might of caused her sudden limp?
She's not off her food and she's letting us examine the leg without fuss, there's also no change in her behavior, she just seems to have started limping.

also, is there anything that we can do to make her more comfortable through the night?

Is it a front or back leg?
It could be any number of things. Fracture, strain, sprain, dislocation, foreign body, ruptured ligament....the list goes on.
She needs to see a vet for diagnosis and treatment, sooner rather than later. If she was mine, she would be going to a vet now. It would be awful if it was left until tomorrow and turned out to be a fracture.
Whatever the cause, if there is swelling or she is limping it will be painful, so she will need an anti-inflammatory.
Let us know how she gets on xx

She hasnt had a VHD Vaccination in the last few days has she ?

She had mixo about four days ago

Hmmmmmmmmm well I have not heard a a post Myxo Vac limp but there is DEFINATELY a post CYLAP VHD Vac limp.
I guess its not beyond the realms of possibility for it to occur with the Myxi Vac but it seems much less likely :?

If she really cant be taken to a Vet this evening I would definately keep her confined overnight to prevent her doing any more damage to the limb.

If it was my baby I'd take her up to the emergency vet in walkden, but they don't have a car and my car has a flat and I can't get a spare till tomorrow
She's in the hutch though and we've removed anything that she could jump on or off.
