Mazie is 3 1/2 months. She got rabies vaccination 4 days ago and is still limping on her left hind leg. Is this normal?

We took her to the vet a day after her vaccination when she kept whining and could not stand on her own. The vet gave her a vaccination for the pain. 4 days later she is still limping and having trouble getting up and sitting down. I'm hoping it is nothing serious and she is just sore and stiff from the vaccination.
Any suggestions?
