I have JUST got off the phone with the vet. The x-rays showed NOTHING - no bone injury, no swellings or problems with discs, nothing to indicate any sort of injury. They didn't do the muscle biopsies, as its rather an invasive and complex procedure which would be painful for Nellie, and may not tell them much anyway.
So they have moved to plan B - which was to take bloods to test for Lymes, and two other similar parasitic infections which can cause what they termed "shifting illness" - generalised muscle and joint pain, depression, fever, weakness in the hindquarters and intolerance to exercise.
They briefly considered another condition - the name of which escapes me - which also presents with intolerance to exercise and weakness, but dogs with that condition actually collapse and pass out, so they are not convinced on that one.
They admitted that parasitic infection is unlikely, but they want to rule it out - and if she DOES have something like that, it is treatable with prolonged antibiotics. And at least they know what they are dealing with.
And if the bloods come back with nothing? Plan C - referral to either London or Bristol university hospitals (I can choose), where she would go in as a day case and they would do a full work up on her to look for auto-immune disease, amongst others.
Phew, my head is whirling a bit. At least we know that she is not injured, she just feels very unwell - and as such, the vet said she should do as much exercise and running about as she wants, with careful monitoring and rest when she seems to need it.
