Sciatica and Back Nerve Discomfort: Causes, Self-Care Tips and When to See a Doctor

Understand the nerve that runs from your back to your feet.

Quick answer

Sciatica describes discomfort, tingling or numbness that travels along the sciatic nerve from the lower back through the buttock and down the leg, usually on one side. Common causes include a bulging or herniated disc, spinal stenosis (narrowing of the spinal canal), bone spurs and muscle tightness. Most cases improve with time, staying gently active, heat or cold, posture changes and physical therapy. Loss of bladder or bowel control, numbness in the groin or worsening leg weakness are emergencies.

Key takeaways

Sciatica is one of the most common forms of nerve discomfort. Knowing what's behind it helps you manage it sensibly.

Understanding sciatica

The sciatic nerve

The body's longest nerve, formed from roots in the lower spine and running down each leg.

What irritates it

Disc bulges, spinal stenosis, bone spurs or tight muscles can press on the nerve roots.

Typical sensations

Shooting, burning or tingling down one leg, often worse when sitting.

Self-care that helps

ApproachTip
Stay gently activeShort walks rather than bed rest
Heat or coldCold early on, heat later
PostureAvoid long periods of sitting
StretchingGentle hamstring and piriformis stretches
Physical therapyGuided strengthening and mobility

Supporting comfort and calm

Stress and poor sleep can make nerve discomfort feel worse. NerveCalm's corydalis supports comfort, and its California poppy and passion flower support relaxation and sleep, alongside the treatment plan your doctor or physical therapist recommends.

Seek urgent care for loss of bladder or bowel control, numbness in the groin or inner thighs, or rapidly worsening leg weakness. See a doctor if sciatica lasts more than a few weeks or follows an injury.
