People diagnosed with restless leg syndrome may have abnormally high amounts of bacteria living in their small intestines. This is brought on by a condition commonly known as small intestinal bacterial growth or SIBO.
Regular, moderate exercise is usually prescribed as a treatment for easing your RLS symptoms. For example, taking a short, easy walk before bedtime and doing some gentle stretching may help. However if your exercises are too rigorous it may make your overall symptoms worsen.
