I Have Crps Type 2 For What Will Be 5

I have crps type 2 for what will be 5 years in October 2015. It was ignored by employer and their doctors so it was not treated properly in the early stage. I have a stimulator now. But I'm not getting enough relief to reverse anything. But there has been some improvement in pain. So what can I expect in the coming g years with my crps type 2?
