Let me give an example. if Bacon had a completely severed achilles tendon she would not be able to put any weight on her left hind foot and it would flop if she did try to weigh bear. Any veterinarian can diagnose a completely severed Achilles tendon just by palpating it. Surgery would be the only option.
If it was a bad tear she could not jump up onto something. If she could walk at all it would be with a pronounced limp. Sometimes cage rest and putting the leg in a cast would be the treatment of choice.
If the tear was minor cage rest might be all that she would need.
So here, the severity of damage to the same tendon has completely different ways of treating it.
Neurologic damage can be the same way.
You need a diagnosis for the best choice of treatment.
And you need a diagnosis to find out if she absolutely needs surgery to completely regain all function or would some lesser (and less expensive) treatment might give her reasonable function.
The anti-inflamatory medication might be all she needs if she has temporary nerve irritation.
That is why i suggested that you give her medications time to work.
I hope that this has helped.
