Successful treatment of restless legs syndrome accompanied by headaches for 30 years with herbal prescriptions containing Paeoniae Radix: A case report

Background

Restless legs syndrome (RLS) is a neurological disorder that causes unpleasant symptoms in the legs when resting, which are relieved by movement. Pharmacotherapy is the standard treatment. However, current treatment provides only symptomatic relief and may result in adverse effects with long-term use. Treatment protocols using herbal medicines have emerged to compensate for this limitation.

Case presentation

A 70-year-old Asian woman visited our hospital with worsening headaches that had persisted for 30 years. Her headaches were aggravated by night-time lower-extremity discomfort. The patient was diagnosed with RLS based on the 2012 Revised International Restless Leg Syndrome Study Group Diagnostic Criteria (IRIS). The patient was prescribed herbal medicines, Shihogyeji-tang, Gyejibokryeong-hwan, and Jakyakgamcho-tang, all of which contain Paeoniae Radix. Fourteen days after starting herbal medicine treatment, the IRIS score decreased from 30 to 18. The patient experienced less leg discomfort. Moreover, her sleep time increased, and her headaches resolved. After 28 days of herbal treatment, the IRIS score decreased to 9. Importantly, the patient reported no sleep disturbance or headaches. Subsequently, conventional medications were discontinued. The patient remained stable (IRIS score: 9–10). Herbal treatment was discontinued on day 163. At the last follow-up, (day 364), the patient has not reported any symptom recurrence.

Conclusions

We described a female patient with a 30-year history of RLS symptoms and related sleep disturbances that induced chronic uncontrolled headaches, who experienced improvements shortly after using herbal medicines containing Paeoniae Radix. Conventional medications were discontinued and the patient had no recurrence of symptoms. Considering these, herbal medicines containing Paeoniae Radix may be a suitable alternative treatment for RLS and its related symptoms.
