I rub some peppermint oil on my legs and massage it in for a few minutes when I'm experiencing restless leg syndrome (urge to move feet and legs, uncomfortable sensations, pain and soreness) which can interfere with sleep as well.
I make the oil myself with any matter of carrier oil (olive, etc) some drops of peppermint, wintergreen and birch as they contain natural salicate acid similar to aspirin to neutralize pain. I also add some drops of frankencense to bring on relaxation and alleviate anxiety.
