The short explanation
Yes, there is a real link. An uncomfortable urge to move the legs, usually in the evening or at night and relieved by moving, is called restless legs syndrome. Low iron stores in the body, even without anaemia, are one of the known contributors, so doctors often check ferritin in people with these symptoms. Other things can contribute too, such as pregnancy, kidney problems, some medicines, and a family tendency. If your ferritin is low, correcting it may ease symptoms for some people. A doctor can also suggest other ways to manage symptoms and improve sleep.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Caffeine, alcohol and smoking can worsen symptoms in some people.
- Restless legs often run in families and can begin in midlife.
- Poor sleep from restless legs can affect mood, energy and work, so it is worth treating rather than tolerating.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether you have restless legs syndrome or why. A doctor will ask about your symptoms and may check iron, kidney and other blood tests.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Can we check my ferritin as well as haemoglobin?
- Could any of my medicines be making this worse?
- What else can help me sleep better?
- Should I see a neurologist if it continues?
When to seek help

Whatever you choose is filed against this version of the answer, never against you, and it is never shown as a count.
“Explain more simply” asks you which part was hard to follow, so the author knows what to rewrite. “My question is different” opens a private follow-up with this answer attached.
