Mary,
Specialists, it seems, often are reluctant to prescribe LDN because they want to see clinical trials, and there are none for LDN and PD. Your best bet is to find a general practitioner or alternative minded doctor, and take some printouts from the website at
www.lowdosenatrexone.org with you. My family has found two general practitioners who will prescribe it. They seem more openminded and are more likely to say it can't hurt you and are willing to see if it will help you.
And here are some sites you can go to where someone has put together some ldn info packets for doctors. These are more specific to MS but may still be helpful.
