امرأة تشتكي إحساساً مزعجاً في الساقين ليلاً مع رغبة شديدة لتحريكهما يخف بالحركة. أي تحليل مهم؟

A woman reports an unpleasant sensation in her legs at night with an urge to move them, relieved by movement. Which test matters?

1. Ferritin (iron stores)
2. Serum prolactin level
3. Vitamin C level
4. Cardiac enzyme levels

Answer: A) Ferritin (iron stores). Restless legs syndrome is linked to iron deficiency, so ferritin is checked and iron replaced if low. Aggravating drugs such as some antihistamines and antidepressants are reviewed and sleep hygiene advised.
