This has been a constant battle for me for about a month now! My RSD is in my right lower leg... But I experience the exact same problems. The only thing that I have found to help me is to stand up straight until it calms down. I have also found that going outside in the cold air helps to relax the limb too. But if your like me you have to be careful because my leg doesn't recognize how cold it actually is. Good luck... Wishing you many nights of uninterrupted sleep!
