What is restless legs?
Restless legs syndrome (RLS) is a neurologic disorder causing uncomfortable sensations in the legs (sometimes arms) and an irresistible urge to move, mostly at rest or at night. Affects about 7% of US adults.
Iron deficiency is found in many cases and treating it can substantially improve symptoms. Medications work well for refractory cases.
Do I have restless legs? Common signs
If most of these describe what you're experiencing, telehealth may be a good next step:
What causes it
Often unknown. Iron deficiency in the brain (even with normal blood iron) is common. Pregnancy, kidney disease, diabetes, peripheral neuropathy, multiple sclerosis. Family history (50% of cases). Certain medications worsen it (some antidepressants, antihistamines, antipsychotics).
Is it contagious?
No.
Check ferritin — if it's under 75 ng/mL, iron supplementation alone can dramatically improve RLS without any other medication.
Can it be treated online?
RLS is well-suited to telehealth — symptoms are characteristic and treatment is straightforward. Severe refractory cases may benefit from sleep medicine. Significant neurologic symptoms or other concerns need in-person evaluation.
How restless legs is treated
Check and correct iron — ferritin target ≥75 ng/mL. Gabapentin or pregabalin first-line for moderate-severe. Dopamine agonists (pramipexole, ropinirole) effective but risk of augmentation (paradoxical worsening). Opioids reserved for severe refractory cases. Avoid worsening medications.
Self-care while you wait
- Eat iron-rich foods (red meat, beans, leafy greens) — pair with vitamin C
- Limit caffeine, especially afternoon and evening
- Limit alcohol
- Avoid medications that worsen RLS
- Regular moderate exercise
- Massage and stretching
- Hot or cold compresses on legs
- Maintain regular sleep schedule
How long does it last?
Chronic but well-controlled with appropriate treatment.
Frequently asked questions
Why does iron matter?
Iron is needed for dopamine production in the brain. Brain iron deficiency drives RLS even when blood iron is normal.
What's augmentation?
Long-term use of dopamine agonists can paradoxically worsen RLS — symptoms start earlier in the day, more body areas affected, more intense. Why these are now second-line.
Will magnesium help?
Mixed evidence — some patients improve. Worth trying alongside other treatments.
Can my kids get it?
Strong genetic component — risk elevated with family history.
Is it the same as periodic limb movements?
Often overlap — periodic limb movements are during sleep without conscious awareness. RLS is awake symptoms.
