Hi Kim,
I haven't been rejected by a PM doc 'per se' but my previous PM doc said she had nothing left to offer me as I didn;t go along with her constant insistance that I have a spinal cord stimulator..She was not an anasthesiologist and didn't have the knowledge nor the ability to pursue other options! She suggested I seek out other PM docs. We had a mutually agreed -upon parting....

I was, however, rejected by the ortho surgeon who did my ankle surgery...his post op care was terrible and never took my complaints of excessive pain/burn seriously...
I had asked him in June of 2008 if he thought I had RSD..he said "no"
Then in August, it was obvious that that was exactly what I had...
he referred me to the above PM doc and then he closed the book on me to any future appts. I was shocked and angry
I finally sought out another attentive podiatrist who took a great interest in everyting I had to say...he actually e-mails me when I have a question or concern !!..and he writes letters to the WC insurance as he gets very frustrated when they decline his recommendations...
Can your GP or your neuro write your scripts until you find a PM doc that you can relate to?
Your current PM who told you to walk backwards uphill on the treadmill is hazardous and needs some RSD training ASAP!! I hope you find another PM doc soon!!
