Restless Legs Syndrome: Understanding the Causes, Symptoms, and When Chiropractic May Help

Is It Really Restless Legs Syndrome—Or Could It Be Something Else?

Have you ever climbed into bed, ready to finally get some sleep, only to feel an overwhelming urge to move your legs?

Maybe it’s a crawling sensation.

A tingling feeling.

An ache deep inside your calves.

Or perhaps you simply can’t get comfortable until you get up and walk around.

If that sounds familiar, you may have Restless Legs Syndrome (RLS).

But here’s something many people don’t realize.

Not everyone who thinks they have Restless Legs Syndrome actually does.

In our office, we occasionally evaluate patients whose symptoms turn out to be sciatica, lumbar nerve irritation, spinal stenosis, peripheral neuropathy, or other conditions affecting the nerves of the legs. These problems can mimic Restless Legs Syndrome because they create tingling, burning, aching, or an irresistible urge to move the legs.

That’s why a thorough examination is so important.

The right treatment begins with the right diagnosis.

What Is Restless Legs Syndrome?

Restless Legs Syndrome (also called Willis-Ekbom Disease) is a neurological condition characterized by an irresistible urge to move the legs.

Unlike muscle cramps, people with RLS usually describe strange sensations that occur deep inside the legs.

Common descriptions include:

• Crawling
• Creeping
• Pulling
• Tingling
• Buzzing
• Itching beneath the skin
• Aching
• Electric sensations

The hallmark of RLS is that movement temporarily relieves the symptoms.

Walking around the house, stretching, or simply moving the legs often helps—but unfortunately, only for a short time.

Because symptoms usually become worse during periods of rest, they commonly interfere with falling asleep and staying asleep.

Who Develops Restless Legs Syndrome?

Restless Legs Syndrome affects millions of Americans.

It becomes more common with age, although younger adults and even children can develop it.

Women are affected more often than men.

Some people experience occasional symptoms, while others struggle almost every night.

Poor sleep often becomes the biggest problem.

Many patients tell me they aren’t exhausted because of pain.

They’re exhausted because they haven’t slept well in months.

What Causes Restless Legs Syndrome?

The truth is that there isn’t one single cause.

Researchers believe several factors may contribute.

Brain Chemistry

One of the strongest theories involves dopamine, a neurotransmitter responsible for controlling smooth muscle movement.

Disruptions in dopamine signaling appear to play an important role in many people with RLS.

Iron Deficiency

Even when someone isn’t anemic, low iron stores—particularly within the brain—may contribute to symptoms.

This is one reason physicians sometimes order iron studies when evaluating persistent Restless Legs Syndrome.

Family History

Many people with RLS have close relatives who experience similar symptoms.

Genetics appear to increase susceptibility.

Pregnancy

RLS commonly develops during pregnancy, especially during the third trimester.

Fortunately, symptoms often improve after delivery.

Medical Conditions Associated with RLS

Several health conditions are linked with Restless Legs Syndrome, including:

• Diabetes
• Kidney disease
• Peripheral neuropathy
• Parkinson’s disease
• Iron deficiency
• Certain autoimmune disorders

Some medications may also worsen symptoms.

Conditions That Can Mimic Restless Legs Syndrome

This is one of the reasons an accurate diagnosis matters.

Several musculoskeletal and neurological conditions produce symptoms that feel remarkably similar to RLS.

Lumbar Disc Problems

A bulging or herniated disc can irritate spinal nerves traveling into the legs.

Patients often describe tingling, aching, burning, or unusual sensations that become worse while sitting or lying down.

Sciatica

Sciatica occurs when the sciatic nerve becomes irritated.

Pain, numbness, tingling, or burning can travel from the lower back into the buttock and down the leg.

Many people mistake this for Restless Legs Syndrome.

Lumbar Spinal Stenosis

Spinal stenosis narrows the spaces surrounding spinal nerves.

Pressure on these nerves may produce discomfort, weakness, numbness, or unusual leg sensations.

Peripheral Neuropathy

Peripheral neuropathy often causes:

• Burning feet
• Tingling
• Numbness
• Electric sensations
• Pins and needles

Unlike classic RLS, neuropathy symptoms are not always relieved by movement.

Muscle Tightness and Joint Dysfunction

Restricted movement within the lower back, pelvis, or hips may increase muscular tension and alter normal nerve function.

Although this isn’t true Restless Legs Syndrome, it can certainly contribute to nighttime discomfort.

How Is Restless Legs Syndrome Diagnosed?

There isn’t a single blood test or X-ray that diagnoses RLS.

Diagnosis is usually based on your symptoms.

Healthcare providers look for four classic characteristics:

• An urge to move the legs
• Symptoms that begin during rest
• Relief with movement
• Symptoms that become worse during the evening or night

Additional testing may be recommended to rule out other conditions.

Medical Treatment Options

Treatment depends on the underlying cause.

Recommendations may include:

• Correcting iron deficiency
• Reviewing medications
• Improving sleep habits
• Regular exercise
• Stretching
• Prescription medications that affect dopamine or nerve signaling

Lifestyle changes alone significantly improve symptoms for many people.

Can Chiropractic Care Help?

This is an excellent question.

The honest answer is:

It depends on why you’re experiencing the symptoms.

If you have true neurological Restless Legs Syndrome caused primarily by changes in brain chemistry, chiropractic care should not be viewed as a cure.

However, many patients come to our office believing they have Restless Legs Syndrome when the real problem is something different.

If your symptoms are caused—or made worse—by spinal dysfunction, lumbar disc problems, nerve irritation, reduced mobility, or mechanical stress on the lower back, chiropractic care may help improve function and reduce irritation affecting the nerves traveling into the legs.

How Cox® Technic Flexion-Distraction May Help

At O’Hara Family Chiropractic, one of the techniques we frequently use for disc-related conditions is Cox® Technic Flexion-Distraction, a gentle form of spinal decompression.

This treatment is designed to:

• Reduce pressure within spinal discs
• Improve spinal motion
• Reduce mechanical stress on irritated nerves
• Improve flexibility
• Help patients move more comfortably

If lumbar nerve irritation is contributing to leg symptoms, reducing that irritation may help decrease discomfort.

Every patient is different, which is why a thorough examination comes first.

Healthy Habits That May Improve Symptoms

Whether your symptoms are true Restless Legs Syndrome or another nerve-related condition, healthy lifestyle habits often make a difference.

Consider:

• Staying physically active
• Walking daily
• Gentle stretching before bed
• Drinking plenty of water
• Limiting excessive caffeine late in the day
• Maintaining consistent sleep schedules
• Managing stress
• Following your treatment recommendations

Small daily habits often produce meaningful long-term improvements.

When Should You Seek an Evaluation?

Don’t ignore persistent symptoms.

If your symptoms:

• Keep you awake at night
• Are becoming more frequent
• Include weakness
• Cause numbness
• Affect only one leg
• Begin after a back injury
• Travel from your back into your leg

it is important to determine whether something more than Restless Legs Syndrome is occurring.

An accurate diagnosis allows the right treatment plan to begin.

Our Philosophy at O’Hara Family Chiropractic

One of the most important things we do isn’t simply treating symptoms.

It’s helping patients understand why those symptoms are occurring.

Not every restless leg is Restless Legs Syndrome.

Not every tingling sensation is neuropathy.

Not every aching leg comes from arthritis.

Our goal is to identify the source of the problem whenever possible and develop a treatment plan that addresses the cause—not simply the symptoms.

Because when you understand the problem, you’re much more likely to find the right solution.

Final Thoughts

If you’ve been struggling with restless legs, nighttime tingling, burning sensations, or discomfort that interferes with your sleep, don’t assume you know what’s causing it.

There are many possible explanations, and many of them can look remarkably similar.

Whether your symptoms are related to Restless Legs Syndrome, sciatica, spinal stenosis, lumbar disc irritation, or another condition, a proper evaluation is the first step toward getting answers.

At O’Hara Family Chiropractic, we’re committed to helping our patients understand what’s happening in their bodies and providing honest, evidence-informed care tailored to their individual needs.

Sometimes the answer is chiropractic care.

Sometimes it’s another medical condition that deserves further evaluation.

Either way, finding the correct diagnosis is where real healing begins.

Frequently Asked Questions

Is Restless Legs Syndrome the same as sciatica?

No. Restless Legs Syndrome is a neurological disorder characterized by an urge to move the legs, especially at night. Sciatica results from irritation of the sciatic nerve and typically causes pain, numbness, or tingling that travels from the lower back down one leg.

Can dehydration make restless legs worse?

While dehydration is not considered a direct cause of RLS, staying well hydrated supports healthy muscle and nerve function. Some people report fewer nighttime muscle symptoms when they maintain good hydration.

Does walking help Restless Legs Syndrome?

For many people, yes. Gentle walking or stretching often provides temporary relief because movement reduces symptoms while you’re active.

Can chiropractic cure Restless Legs Syndrome?

There is no evidence that chiropractic care cures true Restless Legs Syndrome. However, chiropractic evaluation and treatment may benefit patients whose symptoms are actually related to spinal dysfunction, nerve irritation, or conditions that mimic RLS. Be cautious of anyone who promises a cure.
