Restless Legs Syndrome (RLS) is a common neurological disorder that often starts or worsens during the menopause transition. In short: if you feel a near-irresistible urge to move your legs in the evening or at night, especially at rest, and movement brings relief, there are treatments that work — starting with checking your iron.

What the urge actually feels like:

RLS is easier to recognise than to describe. People reach for whatever words they have: crawling, creeping, fizzing, tingling, an itch deep inside the leg, a feeling that the leg is not quite theirs, an urge to stretch or tense the muscles. Some describe an internal restlessness rather than a sensation at all — a sense that the legs will not settle until they are moved.

Two features separate it from ordinary aches. First, it is an urge rather than simply a pain: the overwhelming sense is that you must move the leg, and movement brings relief, at least for a while. Second, it keeps to a timetable. It arrives or worsens when you are at rest, and it is at its worst in the evening and at night. Sitting still through a film, a long meeting or a car journey can bring it on.

The sensation is real. It is not imagined, it is not a sign of being unable to relax, and it is not a failure of willpower. It is generated in the nervous system, and it responds to treatment.

How common it is in menopause:

RLS affects about 5-10% of the general population and is more common in women. During perimenopause the prevalence rises to 20-25%. The SWAN Study confirmed that the menopause transition is a high-risk window — probably a combination of hormonal fluctuations, fragmented sleep, and low iron stores. Untreated, RLS can steal hours of sleep and drain your daytime energy, focus and mood.

How restless legs and poor sleep feed each other:

RLS and poor sleep damage each other, and the loop is easy to underestimate.

The urge is strongest in the evening, just when you want to settle. So you put off going to bed, or you get up again shortly after you lie down. Once you are asleep, the symptoms can wake you. The night gets shorter. The next day you are tired, flat and irritable.

Then the second half of the loop closes. Fatigue makes RLS worse. A bad night lowers the threshold for symptoms, so the following evening the urge tends to arrive earlier and more strongly. After a run of such nights it becomes hard to say which problem started first.

Two practical points follow. A steady sleep routine is not a soft measure here; it is part of managing the condition. And when someone's main complaint is insomnia, it is worth asking whether an evening urge to move is part of the picture, because the two need different handling.

Why it happens around menopause:

Oestrogen influences dopamine signalling, and dopamine dysfunction is central to RLS. Hormonal fluctuations may unmask a latent tendency or worsen existing RLS. Just as important: many perimenopausal women have heavy periods and, as a result, low iron stores. Iron is needed to make dopamine, and iron deficiency is a major trigger — and a fixable one.

How to recognise it (IRLSSG criteria):

There are five criteria, and all must be met: 1) an urge to move your legs, often with unpleasant sensations; 2) symptoms begin or get worse at rest; 3) they are partly or fully relieved by movement; 4) they are worse in the evening or at night; 5) they are not explained by another condition. If the sensation only happens in one position and disappears as soon as you move, it is almost certainly RLS.

What can worsen or mimic RLS:

Common aggravators: iron deficiency, alcohol, caffeine and tobacco in the evening, certain medicines (sedating antihistamines, some antidepressants, antipsychotics), sleep deprivation, pregnancy, kidney disease and diabetic neuropathy. Mimics: nocturnal leg cramps (pain, not an urge to move), neuropathy (more constant burning or numbness), akathisia (inner restlessness of the whole body, usually from medication) and simple uncomfortable positioning. If pain is severe and comes with redness or swelling of the calf, it is not RLS — seek medical help.

The one thing that is not RLS:

The sharpest line on this page is the one between restless legs and a problem in the leg itself. It is worth drawing again, because the two get confused.

RLS is an urge. It comes on at rest, usually in the evening, usually in both legs, and it eases as soon as you move. There is no heat, no swelling, no redness and no tender, tight calf. Between episodes the leg is entirely normal.

A clot in the deep veins behaves in the opposite way. It causes pain, and often swelling, warmth, redness or tenderness, typically in one calf. It does not melt away when you stretch or walk. If you have one painful, swollen, warm calf — particularly if you have recently been immobile or unwell, or have had a clot before — treat it as urgent, not as RLS, and seek medical help rather than waiting to see whether it settles.

First line: iron and habits:

  • Check your ferritin — if it is below 75 mcg/L, iron supplementation under medical supervision is first line. Do not take iron "blind", without a blood test.
  • Cut evening triggers — caffeine, alcohol, tobacco and sedating antihistamines.
  • Exercise moderately and regularly — daily walking reduces symptoms; avoid exhausting workouts late at night.
  • Keep a regular sleep routine — fatigue makes RLS worse, so a stable schedule and a cool bedroom help.
  • During an episode — calf stretching, massage, a warm shower, or mentally engaging activities (a puzzle, a conversation) can "cover" the symptom.
  • Magnesium — evidence is limited, but some women report mild improvement.

Writing down an urge that only appears at night:

RLS is diagnosed from the description, so the description is the test. In the days before your appointment, keep a note of:

  • When symptoms start — the time of day, and what you were doing
  • Whether they affect one leg or both, and whether they have ever reached your arms
  • What the sensation is like, in your own words
  • What relieves it — walking, stretching, massage, a warm shower, distraction — and how quickly
  • What brings it on — sitting still, a long journey, an evening film, lying down
  • How it affects your sleep — how long it takes to settle, and whether it wakes you
  • Your periods, and especially any bleeding that is heavy or prolonged
  • Everything you take, including antihistamines and any supplements
  • Evening caffeine, alcohol and tobacco
  • Whether anyone in your family has similar symptoms
  • Whether your iron has ever been checked, and what the result was

Bring it on paper or on your phone. A written pattern is far more useful than trying to reconstruct months of evenings in a short appointment.

Getting the words out at an appointment:

Symptoms that only appear when you are lying quietly are hard to convey in a bright consulting room. A short, specific opening does most of the work.

Try: "In the evening, when I sit down, I get an urge to move my legs that I cannot ignore. Walking eases it. It is worst when I am resting and it is disturbing my sleep."

Then add the details that matter: how many evenings a week, whether your arms are involved, and what you have already tried. If the sensation is hard to put into words, say so, and describe it by what relieves it instead.

It also helps to say plainly what you are worried about — your sleep, your iron, the possibility of a clot, or all three. Naming the concern is what gets it addressed.

When you need a doctor:

If iron and habit changes do not help, see a sleep specialist or neurologist. Effective prescription medicines exist, but do not self-medicate. It is worth knowing that older dopamine-type medicines can make symptoms worse over time (a phenomenon called augmentation — symptoms earlier, more intense, and spreading to the arms); newer options are often preferred. Also mention any leg movements during sleep or loud snoring — other sleep disorders can coexist.

Does HRT help RLS?

The evidence is limited and mixed, so do not rely on hormone therapy as an RLS treatment. However, if night sweats are fragmenting your sleep, treating them can help RLS indirectly — fatigue and broken sleep make symptoms worse.

Things people are told that are not true:

  • "It is just stress." Stress can make RLS worse, but it does not create the condition underneath. Being told this is one reason women wait years before mentioning it again.
  • "It is your circulation." RLS is a neurological condition, not a problem with the blood supply to the legs. The urge is generated in the nervous system. That is why it keeps to a timetable, and why iron, which the brain needs in order to make dopamine, matters so much.
  • "Everyone gets twitchy legs." The occasional twitch at the end of a long day is common and settles on its own. RLS is different: it is regular, it is worse at rest, and it costs you sleep.
  • "Nothing can be done." This is the most damaging one. There is a clear first step, checking your iron, and effective prescription treatments exist for those who need them.
  • "Iron supplements are harmless, so I will just try some." Iron is not a vitamin to take casually. Without a blood test you may be taking something you do not need, it can cause side effects, and in some people too much iron is harmful.

In short:

RLS in menopause is common and is recognised by an urge to move at rest, in the evening, relieved by movement. Check your ferritin, cut evening caffeine and alcohol, and exercise regularly. If that is not enough, see a sleep specialist — effective treatments exist.
