What should you know about really bad restless legs?

Restless legs can feel like crawling, pulling, tingling, aching or inner agitation. Moving, stretching or walking may ease it briefly, but symptoms can return when you sit or lie down. The pattern commonly interferes with falling asleep and staying asleep. Restless Legs Syndrome is one possible explanation; iron deficiency anaemia, chronic kidney disease, peripheral neuropathy, pregnancy and some medicines can also be relevant. The symptom does not identify a single cause without assessment.

A clinician may ask when symptoms occur, whether movement helps, how sleep is affected, and whether you have numbness, weakness, cramps, bleeding or a history of kidney problems.

Keep regular sleep and wake times, use gentle walking or stretching before bed, and try a warm bath, massage or a heat or cool pack. Limit caffeine, nicotine and alcohol later in the day. Review medicines with a clinician rather than stopping them yourself. Do not start iron supplementation simply because your legs feel restless; blood tests can show whether iron is low and guide safe treatment.

Book an appointment when symptoms repeatedly disturb sleep, spread to the arms, or affect work and mood. Seek prompt care for a new one-sided swollen or painful leg, sudden weakness, loss of bladder or bowel control, severe breathlessness, chest pain, or confusion. Mention pregnancy, kidney disease, heavy bleeding and all medicines because they change the assessment.

Ask whether iron studies, a blood count, kidney tests or a nerve assessment are appropriate. Discuss possible medicine triggers, non-drug measures, and what to do if symptoms return after treatment.
