Hey. Has anyone had their dog start flinching when petting them around the head and neck? She doesn't do it all the time so of course she didn't do it when we were at the vet.

They don't know what's wrong but they don't think it's her disc or a neurological issue. They guessed it's an intense muscle and gave a muscle relaxer a few days ago. That hasn't helped so I wanted to check if anyone has experienced this.
Thanks.
