I have a lot of lower back pain with the pain shooting down both legs at times. Sciatic (sp?) nerves hurt. Chiropractor states that the hips get swiveled and causes this. I have a fair amount of anxiety and shake my legs to burn this off. Your post is interesting because I have both of these symptoms but I have never heard of this before. The anxiety I believe is a result of my Bipolar disorder and I've attributed the sciatic nerve problem with having wrestled for 10 years and having gained 35 extra pounds about 7 years ago all in the standard male beer belly section. I believe all of this could be remedied by frequent exercise. Your situation of course could be quite different or maybe I have this RLS of which you speak.
