Today, we took Maggie to the vet for her shots, and now she feels so sore, she can't even move. She's in too much pain to even lay down. What do we have to do? Can I give something so she can feel better? Can someone suggest a safe type of pain reliever for Maggie? She only weighs six pounds. I don't want see my baby in pain!! Please if someone can help us. Thanks.

PS: Our Vet is already closed for the weekend.
