If you’ve ever felt an uncontrollable urge to move your legs when you’re trying to fall asleep, you’re not alone. For some people, it’s occasional and annoying. For others, it’s constant, exhausting, and life-altering.
According to Dr. Catherine Fernandez Aristy, a sleep medicine physician with Monument Health, and Jessica Hutchinson, CNP, restless leg syndrome, often called RLS, is one of the most common motor-related sleep disorders. And despite how often it’s brushed off, it’s very real.
“It’s not just being restless,” Hutchinson said. “It’s a sensory-motor condition with specific criteria and real consequences.”
What Restless Leg Syndrome Actually Feels Like
RLS isn’t sore muscles or having a long day. It follows a distinct pattern.
People with RLS experience uncomfortable sensations in their legs when they’re resting, especially in the evening or at night. It’s often described as creeping, crawling, buzzing, or a fizzy sensation deep in the legs. The urge to move can feel overwhelming, and movement brings temporary relief.
“If you’re sitting still or lying down and moving your legs is the only thing that helps, that’s a big clue,” Dr. Fernandez Aristy said.
Symptoms usually follow a circadian rhythm, meaning they worsen at night, and they happen multiple times a week. That pattern helps providers distinguish RLS from anxiety, muscle strain, or general restlessness.
Why RLS Is Often Missed
One challenge with restless leg syndrome is that it’s diagnosed clinically. There’s no single test that confirms it.
“We rely on asking the right questions,” Hutchinson said.
Providers look closely at medications, caffeine use, sleep habits, and whether other sleep disorders might be present. RLS can occur on its own or alongside conditions like obstructive sleep apnea, iron deficiency, or dopamine regulation issues.
Children can have RLS too, though symptoms often look different.
“They may ask parents to rub their legs at night or struggle to sit still on long car rides,” Hutchinson said. “Those details matter.”
What Happens When RLS Goes Untreated
The biggest consequence of RLS is fragmented sleep. Even when people spend enough time in bed, repeated awakenings prevent deep, restorative rest.
“That leads to excessive daytime sleepiness,” Dr. Fernandez Aristy said. “Even in patients whose sleep apnea is well treated.”
Over time, poor sleep affects mood, focus, memory, and cardiovascular health. Untreated RLS has been linked to high blood pressure, heart rhythm issues, and increased anxiety and depression.
In children, there’s also a strong connection between RLS and ADHD. Treating one condition often improves the other.
“Sleep affects everything,” Hutchinson said.
Why Treatment Guidelines Have Changed
For years, dopamine agonist medications like ropinirole and pramipexole were commonly prescribed as first-line treatment. That approach has shifted.
“We now know these medications can cause something called augmentation,” Hutchinson said.
Augmentation means symptoms begin earlier in the day, become more intense, and last longer over time. Patients may need increasing doses, which can worsen the condition rather than improve it.
There are also serious side effects.
“I’ve seen impulse control problems like gambling and hypersexuality completely disrupt lives,” Dr. Fernandez Aristy said.
Because of this, newer guidelines recommend a different treatment approach.
What Treatment Looks Like Today
The first step is almost always checking iron levels.
“Restless leg syndrome is often linked to iron deficiency in the brain,” Hutchinson said.
Providers use different iron thresholds for RLS than for the general population. When levels are low, iron supplementation alone can significantly reduce symptoms.
Lifestyle changes can also help.
Regular exercise, consistent sleep schedules, and avoiding caffeine or alcohol in the evening may improve symptoms. Warm baths, stretching, and massage can provide short-term relief.
One important warning stands out.
“If you have restless legs, avoid anything labeled PM,” Hutchinson said. “Many over-the-counter sleep aids contain antihistamines that make RLS worse.”
For patients who don’t respond to standard options or want to avoid medication, newer treatments exist. One is a wearable device that stimulates nerves in the lower legs each night and doesn’t require surgery.
The Emotional Impact Is Real
Both providers emphasized that RLS affects more than sleep.
“I’ve had patients describe symptoms so intense they felt hopeless,” Hutchinson said.
Dr. Fernandez Aristy agreed.
“It can strain relationships, impact mental health, and affect quality of life for the entire household,” she said.
The good news is that effective treatment can dramatically change that trajectory.
When to Talk to a Provider
Their advice is straightforward.
“Talk to your healthcare provider,” Hutchinson said.
Ask about iron testing. Ask about sleep studies if symptoms continue. And don’t accept worsening symptoms as something you simply have to live with.
“There is hope,” Dr. Fernandez Aristy said. “And there are better options now than ever before.”
