Nighttime Leg Cramping Is Not Normal

Why Do Your Legs Cramp at Night?

You’re finally drifting to sleep—and then, out of nowhere, your calf seizes in pain. Sound familiar? You’re not alone. But despite being common, nighttime leg cramping is not normal.

At Sheen Vein Aesthetics and Functional Medicine, we see this often—especially in patients with vein insufficiency, electrolyte imbalances, or poor circulation.

The Common Culprits

  1. Venous Insufficiency – When leg veins don’t return blood efficiently to the heart, fluid and pressure build up, leading to aching and spasms at night.
  2. Electrolyte Depletion – Low magnesium or potassium can trigger muscle irritability.
  3. Nerve Irritation or Restless Legs – Compression or spinal changes can worsen at rest.
  4. Dehydration or Medication Effects – Diuretics and statins are common triggers.

When to Worry

Cramping that occurs several times per week, or is accompanied by swelling, skin changes, or visible varicose veins, may indicate early venous disease—something our team specializes in diagnosing with non-invasive ultrasound.

How Sheen Vein Approaches Leg Cramping

At our St. Louis vein and functional medicine clinic, we go beyond symptom relief. We evaluate:

  • Circulation and vein valve function
  • Electrolyte and micronutrient balance
  • Thyroid, adrenal, and magnesium levels
  • Inflammation and hydration status

Our integrative approach may include:

  • Ultrasound-guided vein treatment for venous reflux
  • Magnesium glycinate or taurinate supplementation
  • Hydration optimization and mineral restoration
  • Compression therapy and circulation support

Simple At-Home Tips

  • Stretch your calves nightly
  • Hydrate with electrolyte-balanced water
  • Avoid sitting or standing for long periods
  • Elevate legs in the evening
  • Add magnesium-rich foods like spinach, avocado, and nuts

The Takeaway

Persistent leg cramps aren’t just “getting older.” They can be your body’s early warning system. Let Dr. Vidal Sheen and his team identify the why—so you can sleep without pain.
