Advice needed

Just after some advice.

My little sausage started showing signs Monday evening, didn’t want to jump and was very uncomfortable, took her to the vets Tuesday and got some anti inflammatory and pain killers.

On Wednesday she then started to cry when being picked up and would only walk a few steps before sitting down. Took her back to the vets where they gave me 2 more types of painkillers. Since then she has been back to her normal self obviously still stopping her from jumping, but there appears to be no pain now. She seems completely fine.

I have an appointment with a specialist Monday but wondering if I should still go as they said they would do an MRI which is £3000, I am insured so I’m not too worried about the cost but obviously there’s limits on insurance so I don’t want to claim £3000 and that’s almost half of what she’s covered so very much in 2 minds on what to do as she is completely herself again now
