What does restless legs syndrome feel like?

Most people describe an uncomfortable urge to move their legs, often with tingling, buzzing, or crawling sensations. It usually gets worse in the evening and improves with movement. Many people recognise this distinctive pattern once it's explained.

Is restless legs syndrome caused by low iron?

Low iron stores are a common contributor. In restless legs syndrome, iron levels that fall within the standard laboratory normal range can still be low enough to contribute to symptoms. Clinicians often look at ferritin levels more closely when assessing possible RLS.

How do I know if I have restless legs syndrome or insomnia?

With insomnia, the main issue is usually difficulty sleeping without the strong urge to move your legs for relief. With RLS, the urge to move your legs is a key clue. Many people have overlapping symptoms, which is why screening helps.

Can restless legs happen with sleep apnoea?

Yes. Some people have both restless legs symptoms and obstructive sleep apnoea (OSA). If you wake repeatedly, snore loudly, or feel unusually sleepy in the day, we'll typically screen for OSA as well.

Is restless legs syndrome serious?

It's usually not dangerous, but it can affect sleep, mood, and quality of life. If symptoms are severe, persistent, or changing, it's worth checking properly with a clinician experienced in sleep disorders.

What is the best treatment for restless legs syndrome?

It depends on the cause. If iron deficiency is contributing, iron replacement can help. Other options exist for more severe cases, but treatment should always be based on a proper clinical review.

When should I seek urgent medical care?

Seek urgent medical advice by calling 999 if you have: sudden severe sleepiness that is new and making it unsafe to stay awake (for example while driving or working) episodes of collapse, blackouts, or weakness triggered by emotions new neurological symptoms (for example seizures, new severe headaches, or new confusion) severe chest pain, severe breathlessness, or rapidly worsening heart or lung symptoms a severe mental health crisis or thoughts of harming yourself or others dangerous sleep behaviours (such as injuring yourself or others while asleep)

Restless legs syndrome symptoms

Do these symptoms sound familiar?

Restless legs syndrome often feels weirdly hard to describe. People use words like crawling, buzzing, tingling, or electric. You might notice:

A strong urge to move your legs when you're resting
Uncomfortable sensations in your calves, thighs, or feet
Symptoms that are worse in the evening or at night
A temporary relief when you walk, stretch, or move
Trouble falling asleep because your legs won't settle
Waking up repeatedly and feeling unrefreshed

If this sounds like you, a quick assessment can help you figure out what's going on.

Some sleep conditions, including sleep apnoea and restless legs syndrome, can sometimes be mistaken for insomnia because they all disrupt sleep in different ways. As part of our Leicester sleep assessment, we screen for these overlapping problems so the underlying cause of your symptoms isn't overlooked.

A key clue

When do your symptoms happen?

Timing matters a lot with restless legs syndrome, and it's something we assess carefully at Leicester Sleep Clinic. The tell-tale moments are often the ones people mention in passing: legs that won't settle on the bus home to Oadby, in the cinema, or once you've finally got onto the sofa for the evening.

More typical of restless legs syndrome	Less typical of restless legs syndrome
Feels worse when you're resting (lying down or sitting still)	Symptoms are the same all day, not just at night
Symptoms are worse in the evening or at night	It feels like constant severe pain rather than an urge to move
You feel relief when you move your legs	Movement doesn't help at all
It comes and goes and may be better on some nights than others	You have progressive weakness, numbness, or new neurological symptoms

Restless legs syndrome is diagnosed based on a specific pattern: an urge to move the legs, symptoms triggered by rest, relief with movement, and worsening in the evening or night.

Other conditions such as leg cramps or nerve problems can sometimes mimic RLS, which is why pattern recognition is important.

If you're not sure if you have RLS, our online assessment can help. Many people have overlapping symptoms, and we help you sort them out safely.

Understanding restless legs syndrome

Why restless legs is often misdiagnosed

Lots of sleep problems look similar at first, and that's why people get stuck for years with the wrong explanation. At Leicester Sleep Clinic, here are common mix-ups we see:

It can look like insomnia

If your legs won't settle, you might lie awake for hours. That looks like insomnia, but the cause may be different.

It can happen alongside sleep apnoea

Some people have both RLS symptoms and breathing-related sleep disruption. If we only focus on one, you may not improve.

Anxiety gets blamed too quickly

Feeling stressed can worsen symptoms, but stress isn't always the root cause.

Iron deficiency often gets missed

People can be told their blood tests are normal even if iron stores are low enough to affect symptoms. That's why targeted screening matters.

At Leicester Sleep Clinic, we screen across the most common sleep disorders so we can guide you to the safest next step.

How to treat RLS

Treatment options for restless legs syndrome

The right treatment depends on what's driving your symptoms and how much they're affecting your sleep. For many people, low iron stores play an important role. When this is the case, carefully supervised iron replacement can help reduce restless legs symptoms over time. Improvement is usually gradual rather than instant.

Some people notice changes within a few weeks
Others improve more slowly over a couple of months
The correct dose and duration matter – more is not always better
Side effects can occur, which is why treatment should be guided properly

If iron deficiency looks likely after clinician review, they will typically explain whether supplementation may be appropriate and guide you through the next steps. Some long-term medications for restless legs syndrome can cause symptoms to worsen over time (a process called augmentation), which is why careful treatment choice and regular review are important.
