All of the published medical opinion on CRPS is that it can spread in 3 different patters. The spread can be of the mirror sort you describe, it can be contiguous - in other words the pain spreads further along the limb where it was originally or it can appear in a completely independent area of your body. There is nothing at all to stop CRPS symptoms appearing in your leg even if it was originally in your arm/hand. If you need evidence of this opinion for any of your docs please go to www.rsds.org and read through all of their clinical guidelines, the Dutch clinical guidelines and the medical articles archive which is an excellent and reputable source of data.

As for your hoarseness, it is impossible to answer this. I know you don't have insurance but it is terribly important to have this investigated. It doesn't sound like anything listed in the published, clinical information available on CRPS symptoms. It could be anything so you need to get it checked out - it may turn out to be just an infection or something else that can be easily treated. Best of luck.
