i got my desert tortoise 6 months ago as a present, she is 13 years old. she had runny nose , eyes closed and didnot eat for the last 2 days. i took her to a vet, he said she had upper respiratory infection like a flu but dangerous for tortoises. he tried to give her medicine in her mouth but she refused. so he injected her with something i dont remember its name to help. but now she is not moving at all and her legs are limp. Is this normal? what can i do? Is she dead? why?
