How can i help myself with restless leg syndrome?

Basically haven’t been properly diagnosed but my mother and mother’s mother both had it, i constantly find myself stretching and flinching and moving my arms and legs and it’s worse at night. It’s sometimes so difficult i genuinely won’t sleep at night and i know there’s no cure. People say you grow out of it but for now is there anything i can do to help with it? I try to distract myself but i really struggle
