What causes restless legs syndrome?

The characteristic pattern is discomfort that begins or worsens while sitting or lying down, improves with movement, and returns after becoming still. It differs from a muscle cramp, which tightens a muscle, and from neuropathy, which may cause persistent burning or numbness. Clinicians ask about sleep, medicines, family history, pregnancy and diet, then may check iron status and kidney function.

Write down the time of day, the sensations, sleep disruption and anything that relieves them. Gentle stretching, regular activity and a consistent sleep routine can reduce triggers for some people. Review medicines with a clinician rather than stopping them yourself. If testing shows low iron, the cause of the deficiency should be explored before iron supplementation is chosen.

Arrange an appointment when symptoms are frequent, impair sleep or interfere with daily activities. Seek prompt care for sudden weakness, a swollen painful leg, chest pain or breathlessness because these symptoms need a different assessment. Ask for earlier advice if symptoms start during pregnancy, follow a medicine change, or occur with marked fatigue or signs of bleeding.

Do my symptoms fit restless legs syndrome? Should we check iron levels and kidney function? Could any medicine, pregnancy or another condition be contributing?
