My dog is hitting her head and whining?

My dog is a Jack Russell mixed with something else. She is four, and looks healthy. She's been in two dogs fights but they were very serious.. Also, main part : She's been hitting her head against the walls outside and whining. When we let her in the house, she stops, but she runs around sniffing everything. So if there is anything wrong or I am just superstitious, please tell me. Thanks !
