Symptoms & causes
Restless legs or neuropathy? How to tell them apart, and why it matters
Both can wreck your evenings and your sleep, and both live in the legs, but they are different problems with different fixes. One question separates them faster than any test: does moving your legs make it better?
Written by the Managing Neuropathy editorial team under the direction of Dr. Tom Biernacki, DPM, FACFAS · Clinical review pending · Last updated 16 October 2026
The short answer. Restless legs syndrome (RLS) is an urge to move the legs, usually with a crawling, pulling or aching feeling deep inside them, that comes on when you sit or lie still in the evening and eases while you move. Neuropathy is numbness, tingling or burning that starts in the toes and soles and doesn’t go away when you walk. You can have both, because nerve damage is one of the conditions linked to RLS. For restless legs, the first step is a blood test for iron, not a sleeping pill.
The quick way to tell them apart
| Restless legs syndrome | Peripheral neuropathy | |
|---|---|---|
| What it feels like | An urge to move, with crawling, pulling, aching or throbbing deep in the legs | Numbness, tingling, pins and needles or burning, mostly in the feet |
| Where | Calves and legs, sometimes the arms | Toes and soles first, both feet, creeping upward |
| When | Evenings and night, when sitting or lying still | Often all day; burning is commonly worse at night |
| Does moving help? | Yes, for as long as you keep moving | No, and long walks can make the feet feel worse |
| Numbness? | No | Usually |
| What the exam shows | Normal feeling and reflexes | Reduced feeling, vibration sense or ankle reflexes |
| First tests | Ferritin and transferrin saturation (iron stores) | Monofilament and vibration testing, glucose, vitamin B12 and other blood tests |
Nighttime leg cramps are the third look-alike: a sudden, painful, hard knot in the calf or foot that eases when you stretch the muscle. Restless legs don’t knot the muscle, and they don’t usually hurt in that sharp way. Leg and foot cramps at night.
Why neuropathy and restless legs travel together
Nerve damage is one of the conditions linked to RLS, along with low iron, kidney failure and pregnancy, so people with neuropathy are more likely to have both. The sensations blend: burning feet that keep you awake, plus an urge to move that won’t let you settle. Treating one and ignoring the other is a common reason people conclude that nothing works.
The overlap has one practical upside. Gabapentin and pregabalin are used for nerve pain and are now first-choice medicines for RLS as well, so one medicine can sometimes help both. That is a decision for your prescriber, not something to start on your own. Medicines for nerve pain.
What sets off restless legs
- Low iron, even without anemia. Low iron in the brain is thought to play a part, even when blood counts look normal.
- Medicines, especially sedating antihistamines, including the ones in many over-the-counter sleep aids, some anti-nausea medicines, antipsychotics and antidepressants that boost serotonin.
- Pregnancy, mainly the last trimester. It usually settles after the baby is born.
- Kidney failure and dialysis.
- Alcohol, caffeine and nicotine, short sleep and sleep apnea.
- Family history. RLS often runs in families.
If a prescribed medicine seems to be the trigger, don’t stop it on your own. Ask your prescriber about alternatives, because some, antidepressants included, need to be tapered.
What helps restless legs
- Get your iron checked properly. Ask for ferritin and transferrin saturation, ideally drawn in the morning, without iron supplements or iron-rich food for 24 hours beforehand. The American Academy of Sleep Medicine recommends iron for adults with RLS, as tablets or an infusion, when ferritin is 75 ng/mL or lower or transferrin saturation is under 20%, and an infusion when ferritin is between 75 and 100. That is a higher bar than many labs flag as low. If your iron is low, your doctor should also find out why. Take iron only under medical guidance, because too much is harmful too.
- Review every medicine and supplement, particularly over-the-counter sleep aids that contain a sedating antihistamine such as diphenhydramine.
- Cut caffeine after midday and alcohol in the evening, and stop smoking.
- Move, stretch and massage. Exercise during the day, a walk or calf stretches when symptoms start, and a short warm, not hot, bath before bed. With neuropathy or diabetes, check the water first with a thermometer (90 to 95°F) or your elbow, dry your feet well afterwards, and skip heating pads on legs and feet that can’t feel heat properly.
- Keep regular sleep hours in a dark, quiet bedroom.
- Medicines, when needed. Gabapentin, gabapentin enacarbil and pregabalin are now the preferred first choices. The older dopamine medicines, levodopa, pramipexole, ropinirole and rotigotine, are no longer recommended for routine use, because over time they can make RLS worse and start earlier in the day, a problem called augmentation. If you take one and your symptoms are spreading or starting earlier, talk to your prescriber, and don’t stop it suddenly on your own.
When to see a doctor
- Symptoms most evenings, or they are costing you sleep.
- Numbness, burning or weakness in the feet. That points to neuropathy, which needs its own workup. Numb feet: the causes and the tests.
- You are pregnant, have kidney disease, or started a new medicine around the time it began.
- You take a dopamine medicine for RLS and the symptoms are starting earlier in the day or spreading to your arms.
- Your bed partner says you kick or jerk your legs in your sleep.
Common questions
Can neuropathy cause restless legs?
Neuropathy is one of the conditions linked to restless legs, so people with nerve damage are more likely to have both. The two can exist side by side, and each needs its own treatment.
How can I tell if it is restless legs or neuropathy?
Ask whether moving helps. Restless legs is an urge to move that eases while you move and comes on at rest in the evening. Neuropathy is numbness, tingling or burning in the feet that doesn’t go away when you walk.
Does iron help restless legs?
Often, if your iron stores are low. Sleep specialists now treat adults with RLS when ferritin is 75 ng/mL or lower or transferrin saturation is under 20%, and may give an iron infusion up to a ferritin of 100, a higher threshold than many labs flag. Get tested before taking iron, take it under medical guidance, and have the reason for any low iron looked into.
Why are my legs restless at night?
Restless legs follow a daily rhythm, peaking in the evening and at night, and they are brought on by sitting or lying still. Low iron, some medicines, alcohol, caffeine and short sleep make them worse.
Does gabapentin help restless legs?
Yes. The American Academy of Sleep Medicine now recommends gabapentin, gabapentin enacarbil and pregabalin as first-line medicines for restless legs. Gabapentin and pregabalin also treat nerve pain, which helps when someone has both.
Are restless legs a sign of something serious?
Usually not, but they can be the first clue to low iron, kidney disease or neuropathy, so they are worth a check-up and blood tests rather than just living with them.

For our Michigan neighbors
Legs that won’t
settle at night?
A foot and ankle exam checks the nerves, the circulation and protective sensation, the first step in working out whether it is neuropathy, restless legs or both. Dr. Biernacki’s Michigan practice can do that, and coordinate with your primary care clinician for the iron tests.
Everywhere else, take this page to your own clinician.
