Restless Legs Syndrome

Restless legs syndrome (RLS), also called Willis-Ekbom disease, is a sensorimotor disorder of the nervous system. It produces an uncomfortable urge to move the legs, typically worse in the evening and at rest, and briefly relieved by movement. The exact cause isn’t fully understood, though it is often linked to dopamine signaling and, in many people, to low iron stores. Because RLS can also accompany other conditions — iron deficiency, kidney disease, pregnancy, or certain medications — evaluation by a physician matters, both to confirm the diagnosis and to check for treatable contributors.

RLS has a recognizable rhythm:

• An urge to move the legs, often with crawling, tingling, or aching sensations
• Symptoms that appear or worsen at rest — sitting or lying down
• Relief, at least briefly, with movement such as walking or stretching
• A clear evening and nighttime pattern that disrupts falling asleep
• Daytime fatigue and low mood that follow broken sleep

Contributors can include low iron, family history, pregnancy, kidney issues, and some medications. However, because addressing an underlying cause — low iron in particular — can change the whole picture, that medical workup remains a priority guided by a physician.

In Chinese medicine, the nighttime restlessness of RLS is often understood in terms of Blood or Yin failing to nourish and settle the sinews, allowing “internal Wind” to stir the legs. The evening timing fits this framework, since night is when Yin should anchor the body. Treatment aims to nourish Blood, calm Wind, and settle the limbs. Acupuncture points along the leg channels — such as Zusanli (ST36), Sanyinjiao (SP6), and Kunlun (BL60) — are commonly associated with this goal, though the specific prescription always depends on the person Dr. Willcox is treating.

For restless legs, acupuncture is used as a possible complement aimed at easing the uncomfortable sensations and supporting better sleep — thought to work partly by engaging the nervous system’s own regulating and pain-modulating pathways. The research is early but encouraging. A randomized controlled trial found that adding acupuncture to standard medication produced greater improvement in RLS symptom scores and sleep quality than medication alone (Raissi et al., Journal of Acupuncture and Meridian Studies, 2017). A 2023 review of several randomized trials pointed in a similar direction, while noting the modest size and quality of the studies. Acupuncture is therefore offered as a possible supportive complement — not a proven treatment and not a substitute for the medical care RLS may require.

A first visit begins with the pattern itself — when symptoms strike, how they affect sleep, and what has been ruled out or tried. Dr. Willcox will ask whether iron levels have been checked and whether a physician is involved, since a treatable cause like low iron changes the approach. Treatment is gentle, often focused on the legs and aimed at evening comfort and sleep. Throughout, acupuncture is coordinated with — never a substitute for — the medical care that manages the condition.
