Yes! I have had RSD for almost two years.It is in both arms,back,legs,and feet.Sciatic nerve pain started about three months ago. I've been undergoing lumbar cortisone injections with some relief. The combination of the two ailments has left me 100 percent disabled. I use a walker most of the time, and am now looking at using an electric scooter to maintain my independence. Numbness,burning pain go hand-in hand with RSD. Circulation problems also. Sometimes it's hard to tell where the RSD ends and the sciatic pain begins(which does go down both legs by the way) I wish you the best. I hope you have a good treating doc. I'm fortunate that I do!
