Wow, I have the same issues, but I'm only 72. After trying all pain medications out there, the only thing that ever helped me was Fentanyl. Unfortunately, the DEA in my town only wants physicians to prescribe for patients who are terminal (i.e., cancer). Right now, I have an upcoming appointment for a possible neurostimulator system.
It doesn't sound like you have a Pain Management Doctor in your area. Even if you did, you'd need a referral from your Doctor. How does your Primary Doctor feel about referring you for Medical Marijuana? There are various options there, from cookies to gummies. If your Primary is willing to prescribe Medical Marijuana, that will provide you with some relief. If your Primary won't even prescribe Medical Marijuana, you could go to a regular Marijuana Dispensary. You won't need a prescription there, but the items will cost a bit more. I know it isn't easy to switch Primary Physicians, but your health is paramount. Find a new Primary who will refer you to a Pain Doctor for help.
