Clarkstar,
It sounds like the PT Dr understood your condition unlike the other dr's that you have recently seen. Unfortunately there are so many Dr's that have never heard or treated a CRPS case. Have you mentioned your current circumstances to the PT Dr that was treating you? Put a message with that Dr and make him aware of the current circumstances and I would think either they could refill or refer you to a Pain Management Dr or someone that is used to treating a chronic pain condition. They are familiar with your case so I would think they would help you.
As far as the people in your life that thinks you shouldn’t take the medicine, I'm not sure what to say. I'm sure they have your best interest at heart but they don’t have to live with the pain. For me, I reached the decision to take pain killers when I knew I no-longer could handle the pain while performing day to day life. I wanted to live some of my life. As far as addiction, I think someone addressed this already but a study showed only 1-3% of pain patients become addicted. I really hate taking meds, but I really have no choice because I would have no life without taking them. With the meds I was able to finish my MBA in one year, hold a job in one of the top 100 public accounting firms for 2.5 years and basically have a life. Without my meds I would be stuck in bed or a wheel chair. Pain medicine is exists to give people their life back when all else fails or until something works for you. Hang in there and I hope your meds issue / treatment plan is resolved in the near future.
