If you’ve ever felt sharp, shooting pain travel from your lower back down your leg, you’ve probably experienced sciatica. It’s one of the most common and recognizable symptoms of nerve irritation in the lower spine.
The good news? Most cases of sciatica improve with time, movement, and self-care. But understanding what’s happening and knowing when to seek medical help can make recovery smoother and less stressful.
What Is Sciatica?
Sciatica isn’t a condition on its own. It’s a set of symptoms that happen when the sciatic nerve — the largest nerve in the body — becomes irritated or compressed. This nerve starts in the lower back, passes through the hips and buttocks, and runs down each leg.
When something presses on or inflames this nerve, pain signals travel along its pathway. That’s why sciatica can feel like back pain, hip pain, or leg pain all rolled into one [1].
For more on conditions that often cause sciatica, see common conditions behind back pain: herniated discs, arthritis, and more.
What Sciatica Feels Like
Sciatica pain varies from person to person. Some people describe it as a dull ache, while others feel sharp, electric-like jolts. Common symptoms include:
Pain radiating from the lower back into the buttock and leg
Tingling or “pins and needles” in the leg or foot
Numbness or weakness in one leg
Pain that worsens with sitting, coughing, or sneezing
Relief when standing up or walking around
Most cases affect only one side of the body. If you notice pain or weakness in both legs, or sudden loss of bladder or bowel control, seek immediate medical care [2].
What Causes Sciatica?
Several conditions can irritate or compress the sciatic nerve:
Herniated Disc
One of the most common culprits. A disc in the lower spine bulges or ruptures, pressing on the nerve root. Learn more in herniated discs and other common conditions.
Spinal Stenosis
Narrowing of the spinal canal reduces space for the nerves, often linked to arthritis and aging. See common conditions behind back pain for details.
Degenerative Changes
Osteoarthritis or bone spurs can put pressure on nerves.
Piriformis Syndrome
A tight or spasming piriformis muscle (deep in the buttock) can irritate the sciatic nerve.
Other Factors
Injury or trauma to the lower back
Pregnancy, due to changes in posture and weight distribution
Tumors or cysts (rare)

Who’s at Risk?
Anyone can experience sciatica, but certain factors make it more likely:
Age (discs and joints naturally wear down over time)
Sedentary lifestyle
Occupations with heavy lifting or long sitting
Obesity (extra weight adds spinal load)
Diabetes (can affect nerve health) [3]
Many of these overlap with everyday habits that trigger back pain, which means lifestyle changes can make a real difference.
How Sciatica Is Diagnosed
Doctors usually diagnose sciatica based on symptoms and a physical exam. You may be asked to:
Walk on your toes or heels to check for weakness.
Lie down and raise each leg (straight leg raise test).
Describe what makes pain worse or better.
Imaging tests (MRI, CT, or X-ray) are sometimes ordered if symptoms are severe, long-lasting, or linked to red flags.
Treatment and Relief Options
Most people with sciatica improve in a few weeks without major medical intervention [4]. The focus is on easing pain, reducing inflammation, and restoring mobility.
1. Keep Moving
It’s tempting to rest in bed, but prolonged inactivity often makes sciatica worse. Gentle activity keeps circulation flowing and prevents muscles from weakening. See best exercises for a healthy spine for safe options.
2. Heat and Ice
Applying ice packs during the first couple of days may reduce inflammation. Heat can help relax tight muscles once initial pain calms down.
3. Medications
Over-the-counter options like NSAIDs can ease discomfort. Stronger medications or injections are sometimes used for stubborn cases [5].
4. Physical Therapy
A tailored exercise program can strengthen the core, improve flexibility, and relieve nerve pressure. Learn what to expect in physical therapy for low back pain.
5. Lifestyle Adjustments
Improving posture and ergonomics protects the spine from repeated strain. Explore ergonomic hacks for home and office.
6. Stress Management
Stress can heighten pain perception and cause muscles to tense up. Breathing techniques or mindfulness may help — see the mind-body connection between stress and low back pain.
When to See a Doctor
Seek medical care if:
Pain lasts longer than a few weeks.
You experience significant weakness, numbness, or tingling in the leg.
Pain is severe and not improving with self-care.
You lose bladder or bowel control (a medical emergency).

Can Sciatica Be Prevented?
Not all cases can be avoided, but many risk factors are modifiable:
Stay active: Regular exercise strengthens the spine and core muscles.
Maintain good posture: Sitting and standing tall reduces disc stress.
Lift safely: Bend at the knees, not the waist.
Prioritize sleep support: See the role of sleep in back health.
Healthy habits are your best defense against future flare-ups.
Bringing It All Together
Sciatica may feel alarming, but for most people, it’s a temporary condition that responds well to movement, ergonomic changes, and self-care. By understanding what causes sciatic nerve irritation — and knowing when it’s time to see a doctor — you can manage symptoms with more confidence.
If you’re experiencing leg pain, tingling, or numbness, don’t ignore the signals. Small adjustments to posture, sleep, and stress levels can make a big difference, alongside professional guidance when needed.
