My hsubands RSD is in his foot and ankle. I buy him diabetic socks at wal-mart. They're super soft and not constricting , I've even bought a couple of pairs for myself. He also heats the bed up with the electric blanket before going to bed, then turns it off because of the night sweats he usually gets. The best sheets I've found are from QVC (Northern Nights flannel sheets) and regular sheets that are at least 400 thread count.
