I was also prescribed a cream similar to that about 4 months ago. The first one did nothing so the doc told me to stop using it. The second one, unfortunatly, landed me in the er for a few days because of a severe allergic reaction unrelated to the rsd but another disorder. But the allergic reaction to it did cause the rsd to spread (I didn't know rsd could spread from allergic reactions). Sorry I haven't been much of a help with this topic. But I do know someone who had some success with the cream.
