Why do my legs ache at night?

Leg aches at night are often caused by muscle overuse, poor circulation, restless legs syndrome, dehydration/electrolyte issues, or nerve pain. When you lie down, you notice these sensations more because there are fewer distractions and blood flow changes.

Common clues:

• Tired, heavy ache: standing, walking, or hard exercise
• Throbbing/heaviness: venous insufficiency, often better with leg elevation
• Urge to move, crawling/tingling: restless legs syndrome
• Cramping/twitching: dehydration or low minerals
• Burning/tingling/aching: neuropathy or sciatica

What may help:

• Elevate your legs for 15–20 minutes before bed
• Drink enough water
• Stretch calves and hamstrings
• Take walking breaks during the day
• Try a warm bath before sleep

Get medical care soon if one leg becomes suddenly swollen, red, warm, or very painful, if pain comes on with walking and eases with rest, or if you have worsening numbness, tingling, or weakness.
