I've had 2 types of RLS for many years and have found cures for both of them.
1. Legs, shoulders or even whole body jerks madly & uncontrollably. I found that, when this starts to come on, it goes away if I tense the muscles in the affected part as hard as I can for a few seconds. The RLS may reappear once or twice but rentensing the muscles does stop it.
2. A vague feeling of restlessness in the legs so that I just can't keep them still. Stroking the effected area for a while (a few seconds to a couple of minutes) gets rid of it. (I also find this helps for arthritis.)
These are 2 cures I've found for myself; you may find similar ones for you.
