Restless Legs Syndrome: Symptoms, Causes and Management
Restless legs syndrome usually causes an urge to move the legs during rest, particularly in the evening or at night.
Restless legs syndrome, or RLS, is a neurological condition that causes a strong urge to move the legs. It often occurs with creeping, crawling, tingling, aching or hard-to-describe sensations.
Symptoms usually begin or worsen while you are resting. They are often strongest in the evening or at night and ease for a short time when you walk, stretch or move your legs. This pattern can make it difficult to fall asleep and may lead to fatigue during the day.
Persistent symptoms need medical assessment because low iron levels, pregnancy, kidney disease, some medicines and other health conditions may contribute. A GP can review these factors and arrange tests when needed.
Could Your Symptoms Be Restless Legs Syndrome?
RLS has a recognisable symptom pattern. The following features usually occur together:
- You feel an urge to move your legs, often with unpleasant sensations.
- The symptoms begin or become worse while sitting or lying still.
- Walking, stretching or moving provides temporary relief.
- The symptoms are worse in the evening or at night.
- Another condition does not better explain the symptoms.
What Does Restless Legs Syndrome Feel Like?
People describe RLS in different ways. The sensations may feel as though they are deep inside the legs rather than on the skin.
Common descriptions include:
- creeping or crawling sensations
- tingling, pulling or buzzing
- aching or deep soreness
- an uncomfortable need to keep moving
- difficulty keeping the legs still
- temporary relief after walking or stretching
Symptoms commonly affect both legs, although one side may feel worse. They usually occur in the calves, shins or thighs. Some people also notice symptoms in their feet or arms.
When Do Restless Legs Symptoms Occur?
Symptoms usually appear during quiet periods. Common triggers include lying in bed, sitting on a couch, travelling in a car or aeroplane, attending the cinema, or working at a desk for a long time.
The discomfort commonly becomes stronger later in the day. Movement may settle it briefly, but symptoms can return when you stop moving.
This pattern can delay sleep or wake you during the night. Repeated sleep disruption may affect energy, mood, concentration and work performance the next day.
What Causes Restless Legs Syndrome?
RLS does not always have one identifiable cause. Some people have primary RLS, which may run in families. Others develop symptoms in association with another health issue or life stage.
Factors linked with RLS include:
- low iron availability or iron deficiency
- pregnancy, especially later in pregnancy
- chronic kidney disease
- peripheral neuropathy
- diabetes
- Parkinson’s disease and some other neurological conditions
- a family history of RLS
- untreated obstructive sleep apnoea
- some prescribed and non-prescribed medicines
Alcohol, caffeine and some antihistaminergic, serotonergic or antidopaminergic medicines may worsen symptoms in some people. However, do not stop a prescribed medicine without first speaking with your doctor or pharmacist.

RLS or Another Leg Problem?
Several conditions can cause night-time leg discomfort or restlessness. The symptom pattern helps guide the diagnosis.
| Symptom pattern | Possible explanation |
|---|---|
| Urge to move during rest, worse at night and relieved by movement | Restless legs syndrome |
| Sudden, painful tightening of a muscle | Muscle cramps |
| Burning, persistent tingling or reduced sensation | Nerve pain or peripheral neuropathy |
| Pain linked with a joint position, injury or physical load | Musculoskeletal leg pain |
| Inner restlessness that affects more than the legs after a medication change | Medication-related restlessness or akathisia |
A health professional should assess symptoms that do not follow the usual RLS pattern.
How Is Restless Legs Syndrome Diagnosed?
There is no single scan that confirms RLS. Diagnosis usually depends on your symptom history and whether the typical features occur together.
Your GP may ask about:
- when the symptoms begin
- whether rest makes them worse
- whether movement provides relief
- how often symptoms disturb your sleep
- your family history
- pregnancy or other health conditions
- your current medicines and supplements
- symptoms that could suggest another condition
Your GP may arrange blood tests, including iron studies. These may assess ferritin and transferrin saturation. Iron decisions for RLS require clinical interpretation, so do not begin iron supplements solely for restless legs symptoms unless a health professional advises you to do so.
A sleep study is not routinely required to diagnose RLS. However, your doctor may consider sleep assessment when another sleep disorder, such as obstructive sleep apnoea, may be contributing.
How Is Restless Legs Syndrome Treated?
Treatment depends on symptom frequency, severity and contributing factors. Medical management remains central when RLS is persistent or significantly disrupts sleep.
Review contributing health factors
Your GP may assess iron status, pregnancy, kidney health, diabetes, neurological conditions and sleep disorders. Treating a contributing condition may reduce symptoms.
Review medicines and common triggers
A doctor or pharmacist can check whether any medicines may be worsening your symptoms. They can also advise whether an alternative is suitable.
Reducing caffeine and alcohol may help some people. Tobacco use and irregular sleep routines may also make sleep disruption harder to manage.
Medical treatment
Prescription treatment may be considered when symptoms are frequent, severe or continue despite simpler measures. The choice depends on your medical history, iron status, symptom pattern and possible side effects.
Some medicines previously used routinely for RLS can cause symptoms to begin earlier in the day, become stronger or spread to other parts of the body over time. This effect is called augmentation. For this reason, current medicine selection and follow-up should occur through a doctor familiar with RLS management.
Can Exercise Help Restless Legs Syndrome?
Regular moderate exercise may support sleep, general health and symptom management. Movement also provides short-term relief during many RLS episodes.
Helpful options may include:
- regular walking
- gentle cycling
- light to moderate resistance exercise
- calf and hamstring mobility exercises
- short movement breaks during long periods of sitting
- a consistent daytime exercise routine
Very intense exercise or hard training close to bedtime may aggravate symptoms for some people. Adjust the timing and amount of exercise according to your response rather than stopping activity completely.
A physiotherapist can help you develop an appropriate program when pain, weakness, injury or reduced mobility makes exercise difficult. See our guide to physiotherapist-led exercise programs.
Can Massage, Heat or Cold Help?
Massage does not treat the underlying neurological cause of RLS. However, some people find that massage, warmth or cold provides temporary relief and helps them settle before sleep.
Strategies worth testing may include:
- a warm bath or shower
- a heat pack wrapped in a towel
- a cold pack wrapped in a towel
- gentle self-massage
- light stretching
- a brief walk before returning to bed
Use heat and cold for short periods and protect your skin. Avoid these treatments when sensation or circulation is reduced unless a health professional has advised that they are safe.
Some people also choose remedial massage or leg massage for associated muscle tension. Results vary, and relief may be temporary.
How Can You Manage Symptoms at Night?
A consistent routine may make episodes easier to manage, even when it does not remove them completely.
- Keep a regular sleep and wake time.
- Reduce caffeine later in the day.
- Avoid heavy alcohol intake near bedtime.
- Take movement breaks during prolonged sitting.
- Use gentle movement when symptoms begin.
- Keep intense training away from bedtime if it triggers symptoms.
- Record symptoms, sleep and possible triggers for two to four weeks.
Sleep difficulties can become a separate problem when they continue for a long time. Read more about sleep strategies and persistent pain management.
When Should You See Your GP?
Arrange a GP review when:
- symptoms repeatedly interrupt your sleep
- symptoms occur several times each week
- poor sleep affects your energy, concentration or mood
- symptoms began after starting or changing a medicine
- you are pregnant and symptoms are difficult to manage
- you have kidney disease, diabetes or a neurological condition
- simple management strategies have not helped
- you are unsure whether the symptoms are RLS
A medical review can help confirm the symptom pattern, identify contributing factors and determine whether further testing or treatment is appropriate.
Seek Prompt Medical Care for Different or Concerning Symptoms
Typical RLS does not usually cause marked swelling, skin colour changes, progressive weakness or constant severe one-sided pain.
Seek prompt medical assessment if you develop:
- sudden swelling, redness or heat in one leg
- chest pain or shortness of breath
- new or progressive leg weakness
- persistent numbness or loss of sensation
- loss of bladder or bowel control
- severe pain that does not ease with movement
How Can Physiotherapy Help?
Physiotherapy is not the primary medical treatment for RLS. However, physiotherapy may be useful when symptoms occur alongside pain, stiffness, weakness, reduced activity or difficulty following an exercise program.
A physiotherapist may help you:
- develop a regular and manageable exercise routine
- modify training that appears to aggravate symptoms
- address related muscle or joint problems
- build strength and mobility after reduced activity
- plan movement breaks for work or travel
- monitor how your symptoms respond to exercise timing and load
Physiotherapists can also identify symptoms that do not fit a typical musculoskeletal presentation and recommend medical review where appropriate.

What to Do Next
If you have not had persistent restless legs symptoms assessed, start with your GP. Ask whether iron studies, a medication review or assessment for another sleep or health condition may be appropriate.
Meanwhile, record when symptoms occur, what provides relief, how often your sleep is disrupted and whether caffeine, alcohol, prolonged sitting or exercise timing affects the pattern.
Consider physiotherapy when pain, injury, weakness or reduced mobility makes regular exercise difficult. Physiotherapy may also help you plan a steady return to movement without repeatedly aggravating associated symptoms.
