When I wanted to see a new PM, I had my meds just filled, so I had plenty of time to see a few new PM's to interview them. In fact, when I made the appointment, I told them that I wanted to interview the new PM, so they made my appointment a bit longer than the standard 15 minutes.
I went in, with my records, and my current bottles and discussed why I came to interview the new PM. In fact, I was surprised at the reaction, but everyone of them that I interviewed was very pleasant and went out of their way to take their time with me. One made a really good impression with me, more so than the others,although all were very nice.
We discussed my current problems, the meds that I was on, I voluntarily showed him the bottles with the dosages. We discussed why I wanted to change and the fact that nothing could be done other than pain meds for me, what other treatments I had tried and then , and more importantly the fact that at that point, he was very honest with me and told me that while he would love to tell me that he could cure me, or offer me some treatment that would alleviate the pain that I live with, he said, I can only continue what you are currently on and then if you need tweaks in dosages, we will take care of that right away. I didn't want to have to go through the hoops that I had already jumped through in regard to injections again or more pt, and I truly appreciated his honesty in regard to my options......so he is the one that I went with.
I haven't regretted my decision to change PM's once since then.
I hope that your experience is like mine.
