My dog fell and now she's whining help?

well my dog is a dare devil. i was holding her and then she jumped out of my arms. she did a flip and then landed on her back. she's whining and she walks fine but she won't stop whining. what do i do?? my mom said she's fine and she's not taking her to the vet but i'm scared. what can i do to help my dog? she's walking fine as i said before but she won't leave my lap and she's whining she's a teacup yorking btw
