I have reported here before about my experiences with my RLS and they seemed very strange to you. Now I have discovered something new that's also weird:
Since I have RLS I need a heating pad in my lower back every night to calm my legs, without this relaxing warmth it is almost impossible to sleep. So I have felt all along that something is wrong in that area of the back and that this has an influence on my RLS. Now a few days ago I was lying in bed at night trying to fall asleep but as usual my legs were restless. Suddenly something snapped in my back as if a tension had been released and immediately my legs stopped moving. Unfortunately it didn't last long and the tension came back and with it my legs started again. Now I followed up and experimented with stretching and mental relaxation exercises and sure enough, IT WORKED! Every time my legs are restless I relax my back and immediately my legs are calm.
