MRCP2-3313
A 40-year-old woman with no significant medical history presents with fatigue and lethargy that have persisted for several years. She reports difficulty sleeping at night and experiences discomfort in her lower extremities at rest, particularly when trying to fall asleep. She also describes an abnormal crawling and itching sensation below the knees that is relieved by walking. There is no history of pain or snoring at night. Despite several tests ordered by her general practitioner, including brain imaging, thyroid function, and haemoglobin monitoring, all results have been normal. She is not taking any medications and is now working part-time due to her symptoms. What treatment would you recommend to alleviate her symptoms, given the likely underlying diagnosis?
