Sciatic Nerve Pain: Symptoms and Relief

What sciatica feels like

People describe sciatic nerve pain as:

• sharp, shooting, burning or electric pain running down one leg
• pain in the buttock that spreads down the back or side of the thigh, often past the knee into the calf or foot
• pins and needles, numbness or a "dead" feeling in part of the leg or foot
• leg pain that is worse than the back pain
• pain that worsens with sitting, bending, coughing, sneezing or straining
• weakness, such as difficulty standing on tiptoe or lifting the front of the foot

It almost always affects one leg. Sciatica in both legs is less common and needs prompt assessment.

Is it sciatica or something else?

What causes sciatic nerve pain

The sciatic nerve forms from nerve roots in the lower spine (L4 to S3). Anything that squeezes or inflames these roots can cause sciatica:

• Herniated disc: the most common cause, especially in people aged 30 to 50
• Spinal stenosis: narrowing of the spinal canal in older adults, causing leg pain when walking or standing that eases with sitting or bending forward
• Spondylolisthesis: a vertebra slipping forward
• Bone spurs from arthritis
• Pregnancy, from posture and ligament changes
• Rare causes: infection, tumors, cysts

For a detailed explanation of the condition, diagnosis and treatment options including surgery, see sciatica (lumbar radiculopathy).

How to relieve sciatica at home

Stay active

Bed rest makes sciatica last longer. Keep up gentle activity such as walking, little and often. Change position every 20 to 30 minutes, because long sitting usually worsens symptoms.

Pain relief

• NSAIDs such as ibuprofen or naproxen can help, following the label dose. Avoid them with stomach ulcers, kidney disease, or if you take blood thinners, without advice.
• Acetaminophen (paracetamol) alone has little effect on sciatica.
• Heat or cold: use whichever feels better, for 15 to 20 minutes at a time.

Gentle stretches

Stop any stretch that makes leg pain or tingling spread further down the leg.

• Knee to chest: lie on your back, bring one knee toward your chest and hold 20 to 30 seconds.
• Piriformis stretch: lying on your back, cross the affected ankle over the opposite knee and gently pull the thigh toward you.
• Prone press-up: lying on your front, push up on your elbows to gently arch the low back. Some people with disc-related sciatica find their leg pain moves back toward the spine (centralizes), which is a good sign.
• Nerve glides: sitting, slowly straighten the knee while lifting the toes toward you, then lower. Repeat gently.

Sleep positions

Lie on your side with a pillow between your knees, or on your back with a pillow under your knees.

How long does sciatica last?

Most episodes improve significantly within 6 to 12 weeks. Pain often eases first, while numbness or tingling can take longer to clear. About 1 in 4 people still have symptoms after 3 months, and recurrences are common. Persistent or severe sciatica may need injections or surgery.

When to see a doctor

See a doctor if pain is severe, you have weakness, symptoms are not improving after 4 to 6 weeks, or you have any red-flag symptoms. A doctor will examine your strength, reflexes and sensation, and may do a straight-leg raise test, lifting your straight leg while you lie on your back. Reproducing leg pain between 30 and 70 degrees suggests a nerve root problem. Imaging is usually not needed unless symptoms are severe, persistent or suggest a serious cause.

Frequently asked questions

What does sciatica pain feel like?

Sciatica usually feels like a sharp, burning or electric pain shooting from the buttock down the back or side of one leg, often below the knee. It may come with tingling, numbness or weakness, and is often worse when sitting, coughing or sneezing.

How long does sciatica take to go away?

Most people improve within 6 to 12 weeks with self-care. Tingling and numbness may take longer than pain to settle. If symptoms are severe or persist beyond 6 to 12 weeks, a doctor may recommend physical therapy, injections or, occasionally, surgery.

What is the fastest way to relieve sciatic nerve pain?

Keep moving with short, frequent walks, avoid long sitting, use heat or ice, and take an NSAID if it is safe for you. Gentle stretches that do not push pain further down the leg can help. Severe pain may need prescription treatment from a doctor.

Should I walk with sciatica?

Yes, if you can. Gentle walking keeps the spine moving and helps recovery. Start with short distances on flat ground. Walking that consistently worsens leg pain, especially in older adults, may suggest spinal stenosis and is worth discussing with a doctor.

When is sciatica an emergency?

Sciatica is an emergency if you develop numbness in the saddle area, difficulty urinating, loss of bladder or bowel control, or rapidly worsening weakness in one or both legs. These can be signs of cauda equina syndrome, which needs urgent surgery.
