Frustrated with Doctor's Lack of Communication and Care

I'm so frustrated with my doctor, he wants me to go to physical therapy, but has not answered me on what physical therapist he wants me to go see, or which one he is going to refer me to. I also talked to him yesterday about my hip not being able to go back into socket, and he recommended muscle relaxers, and when I asked him for a prescription, he just ignored my messages. (private doctor, so I'm able to call/message him) It's so frustrating, I'm in so much pain.
