Overview
What Is Sciatica?
Sciatica is a set of symptoms — usually pain that travels from your lower back or buttock down one leg. It happens when the sciatic nerve, the largest nerve in the body, becomes irritated or compressed.
The pain can feel sharp, burning, or electric. Some people mostly notice numbness, tingling, or weakness in the leg or foot.
Most cases come from a herniated disc, spinal stenosis, or a tight piriformis muscle pressing on the nerve. Long sitting, heavy lifting, and weak core and hip muscles often play a role.
The encouraging news: the majority of sciatica episodes improve within 4–6 weeks with gentle movement, targeted stretching, and posture changes — surgery is rarely needed.
Common Causes
Why Does My Sciatica Hurt?
Herniated Disc
A disc's inner gel pushes out and presses on the sciatic nerve root.
Read about Herniated Disc →Spinal Stenosis
Narrowing of the spinal canal crowds and irritates the nerve.
Read about Spinal Stenosis →Piriformis Syndrome
A tight buttock muscle compresses the nerve as it exits the pelvis.
Read about Piriformis Syndrome →Degenerative Disc Disease
Age-related disc changes narrow nerve openings.
Read about Degenerative Disc Disease →Spondylolisthesis
A vertebra slips forward and pinches a nerve root.
Read about Spondylolisthesis →Prolonged Sitting
Long sitting increases pressure on discs and the nerve.
Read about Prolonged Sitting →Poor Lifting Mechanics
Bending and twisting under load can irritate a nerve root.
Read about Poor Lifting Mechanics →Weak Core & Glutes
Underactive support muscles overload the lower spine.

Not Sure What's Causing Your Pain?
Symptoms from muscle strain, disc issues, nerve irritation, and joint problems often overlap. Our AI assessment asks a short set of questions about where you feel pain, how it moves with you, what makes it better or worse, and your history — then gives you personalized educational guidance and a stretch routine to try. It is not a medical diagnosis.

Mind Your Posture
Stack ears over shoulders and shoulders over hips.
Sleep Supported
Use a pillow between or under your knees for support.
Home Care
Heat vs Ice
When heat may help
- Chronic stiffness or ongoing tightness
- Before stretching or gentle movement
- Muscle spasms and tension
When ice may help
- New injury within the first 24–48 hours
- Swelling or a warm, inflamed area
- After a flare-up from overuse
If pain is severe, worsening, or lasts more than a couple of weeks, check in with a licensed healthcare professional.
