Thanks everyone for your posts.
Missy's got some spunk back today, and she will let me touch her leg, massage it a little, and move it very gently. She moves it around on her own but still isn't stepping down on it. I am going to drop my son off at school and then call my regular vet. I'm thinking that they will likely want to have her in for an xray today. I will update again when I have more news. I really appreciate all of your support and advice. YT is the best. I don't know what I'd do without you all.
