Having restless legs syndrome, is it best to sleep on your back?
There is no particular sleeping position that reliably improves restless leg syndrome. Some experts suggest sleeping with a pillow between the legs, but this approach is of uncertain benefit. Even if a position is found to be particularly helpful, people move around while sleeping so it’s impossible to reliably adopt a single position throughout a night’s sleep.
Standard treatment of this condition includes moderating caffeine intake, getting regular exercise, distraction (such as working on a crossword puzzle), massaging the legs, and application of heat to the legs. A number of medications can also help, including carbidopa-levodopa or gabapentin. If iron levels are low, supplemental iron can be effective as well; the cause of iron deficiency should be investigated.
