Key Takeaways
- Sciatica is nerve-related pain that often starts in the low back and travels through the buttock and down one leg.
- Symptoms typically follow the path of the sciatic nerve and may include tingling, numbness, or weakness along with pain.
- Common contributors include irritation or compression of nerve roots in the lumbar spine, often linked to disc or joint issues.
- Conservative care like targeted exercise, stretching, and manual therapy may help reduce symptoms and improve function.
- New or worsening weakness, bowel/bladder changes, or severe symptoms need prompt medical evaluation.

Frequently Asked Questions
What is sciatica, and why does it usually affect only one leg?
Sciatica is pain (and sometimes tingling or numbness) caused by irritation of the sciatic nerve or the nerve roots that form it in the lower back. Because you have a left and a right sciatic nerve, symptoms often show up on only one side at a time. The discomfort commonly starts in the low back or buttock and travels down the leg.
What are common signs and symptoms of sciatica?
Sciatica symptoms often include a sharp, burning, or electric-like pain that runs from the lower back or buttock down the back of the thigh and sometimes into the calf or foot. Some people also notice numbness, tingling, or weakness in the leg. Symptoms may worsen with sitting, bending, coughing, or prolonged driving.
What causes sciatica pain to flare up?
Sciatica flares often happen when the nerves in the lower back get irritated or compressed. Common contributors include a lumbar disc bulge or herniation, age-related spine changes, tight hip muscles, or prolonged positions that stress the low back (like long sitting). Poor lifting mechanics and sudden increases in activity can also trigger symptoms.
What conservative treatments may help sciatica?
Many people improve with conservative care focused on reducing nerve irritation and restoring movement. Options may include guided stretching and strengthening (especially for the hips and core), activity modification, heat or ice, and manual therapy such as spinal mobilization/manipulation or soft tissue work. A provider may also recommend posture and lifting changes to prevent repeated flare-ups.
When should I see a provider for sciatica?
Schedule an evaluation if your leg pain lasts more than a few days, keeps returning, or limits walking, sleep, or work. Seek urgent medical care if you develop new or worsening leg weakness, numbness in the groin/saddle area, or changes in bowel or bladder control. Those symptoms can signal a more serious nerve problem that needs immediate attention.
