The best thing to do when you are not being paid attention to at your doctors office is to change to another doc.
Hopefully your family doctor will refer you to a pain management clinic or to an orthopedic surgeon and allow you to be given a fair shake.
If you are in pain, it is illegal for them to ignore and not treat you! As a patient that is paying for a service which is very technical you should expect to be treated. If you are ignored, you always have the right to invoke your rights through your individual or state funded insurance company.
It really makes me mad when someone is just simply left in pain and told to go home and rest, it will get better. Its not and it wont until you are properly treated.
Good luck,
