Chronic back pain can make everyday activities difficult, especially when pain travels from the lower back into the buttocks and leg. Sciatica is a type of nerve pain caused by irritation or compression of the sciatic nerve or its nerve roots. Understanding the causes, symptoms, treatment options, and prevention strategies can help you manage sciatica and protect your long-term mobility.
What Is Sciatica?
Sciatica is pain that follows the path of the sciatic nerve, which runs from the lower back through the buttocks and into the legs. It typically affects one side of the body and may cause sharp, burning, shooting, or electric-shock-like pain.
Sciatica occurs when the sciatic nerve or the nerve roots that form it become irritated or compressed. Depending on the underlying cause, symptoms may range from mild discomfort to significant pain, numbness, or weakness.
What Causes Sciatica?
Several conditions can irritate or compress the nerves that contribute to the sciatic nerve. Common causes include:
- Herniated or bulging discs: A damaged spinal disc can press on a nearby nerve root.
- Spinal stenosis: Narrowing of the spinal canal can put pressure on spinal nerves.
- Spondylolisthesis: One vertebra moves out of its normal position relative to another, potentially irritating nearby nerves.
- Bone spurs: Age-related changes in the spine can produce bony growths that narrow spaces around nerves.
- Piriformis syndrome: In some cases, irritation or compression of the sciatic nerve near the piriformis muscle can cause sciatic-type symptoms.
- Injuries: Trauma affecting the lower back or pelvis may irritate nerves.
- Less common conditions: In rare cases, infections or tumors may affect structures around the spinal nerves.
Identifying the underlying cause is important because the most appropriate treatment depends on what is causing the nerve irritation.
What Are the Risk Factors for Sciatica?
Although sciatica can affect people of different ages, certain factors may increase the likelihood of developing it.
Excess Weight
Carrying excess weight can increase stress on the spine and may contribute to spinal changes associated with sciatica.
Physically Demanding Work
Jobs that involve frequent heavy lifting, twisting, bending, or prolonged driving may increase stress on the lower back.
Prolonged Sitting
Sitting for long periods may contribute to poor posture and back discomfort, particularly when combined with limited physical activity.
Age-Related Spinal Changes
Changes in the spine become more common with age and may include herniated discs, bone spurs, or narrowing around spinal nerves.
Diabetes
Diabetes can increase the risk of certain types of nerve damage. People with diabetes should discuss persistent or unusual nerve symptoms with their healthcare provider.

What Does Sciatica Feel Like?
Sciatica symptoms can vary depending on the location and severity of nerve irritation. Common symptoms include:
- Sharp, burning, or shooting pain that travels from the lower back or buttock into the leg
- Pain that usually affects one side of the body
- Tingling or a pins-and-needles sensation
- Numbness in the leg or foot
- Muscle weakness
- Pain that becomes worse with prolonged sitting, coughing, sneezing, or certain movements
- Difficulty performing everyday activities because of pain or weakness
Sciatica is different from ordinary lower back pain because the discomfort typically follows a nerve pathway into the buttock and leg.
How Is Sciatica Diagnosed?
A healthcare provider can determine whether your symptoms are consistent with sciatica by reviewing your medical history and performing a physical examination. Additional testing may be recommended when symptoms are severe, persistent, unusual, or suggest another underlying condition.
1. Medical History
Your provider may ask when your symptoms started, where the pain travels, what makes it better or worse, and whether you have experienced numbness, tingling, or weakness.
2. Physical Examination
A physical examination may evaluate your range of motion, muscle strength, reflexes, sensation, and how certain movements affect your symptoms.
3. Neurological Examination
Your provider may check reflexes, muscle strength, sensation, and other neurological functions to identify possible nerve involvement.
4. Imaging Tests
Imaging is not always necessary for uncomplicated sciatica. However, an X-ray, MRI, or CT scan may be considered when symptoms persist, are severe, or when a structural problem needs further evaluation.
- X-ray: Can help identify certain bone or spinal changes.
- MRI: Provides detailed images of discs, nerves, and other soft tissues.
- CT scan: Can provide detailed images of the spine and may be used when MRI is not appropriate or available.
5. Electromyography (EMG)
In selected cases, an EMG and nerve conduction studies may help evaluate nerve and muscle function and determine whether a nerve is being affected.
What Are the Treatment Options for Sciatica?
Sciatica treatment depends on the underlying cause, severity of symptoms, and how long the pain has been present. Many people improve with conservative treatment and do not require surgery.
1. Physical Therapy
Physical therapy may help improve strength, flexibility, mobility, and posture. A physical therapist can develop an individualized exercise program based on your symptoms and physical condition.
2. Medications
Depending on your health history and symptoms, a healthcare provider may recommend medications to help manage pain or inflammation. Do not start prescription medications or regularly use pain relievers without discussing them with a qualified healthcare professional.
3. Heat and Cold Therapy
Cold or heat may provide temporary relief for some people. A cold pack may help with acute discomfort, while heat can help relax tight muscles. Use a protective layer between your skin and the heat or cold source.
4. Lifestyle and Activity Changes
Remaining appropriately active is generally preferable to prolonged bed rest. Gentle movement and activities recommended by your healthcare provider may help maintain mobility while you recover.
5. Injections
For some people with persistent symptoms, a healthcare provider may recommend an injection around an irritated spinal nerve to reduce inflammation and pain.
6. Surgery
Surgery may be considered when severe nerve compression causes persistent symptoms, significant weakness, or pain that does not improve with appropriate nonsurgical treatment. Procedures such as a discectomy or decompression may be used depending on the underlying problem.
How Can You Relieve and Prevent Sciatica Pain?
Managing sciatica often involves more than treating pain during a flare-up. Healthy daily habits may support spinal health and reduce strain on your back.
1. Improve Your Posture and Ergonomics
When sitting for extended periods, use a chair that supports your lower back and keep your feet comfortably supported. When working at a computer, position the screen at an appropriate height and avoid prolonged awkward postures.
When lifting objects, bend at your hips and knees and avoid twisting while carrying heavy loads. If an object is too heavy, ask for assistance.
2. Stay Physically Active
Regular physical activity can help maintain muscle strength and flexibility. Walking and other low-impact activities may be appropriate for many people, but exercises should be adapted to your symptoms.
A healthcare professional or physical therapist can recommend stretches and strengthening exercises that are appropriate for your condition.
3. Maintain a Healthy Weight
If you are overweight, gradual weight management may reduce stress on the spine. A balanced diet and regular physical activity can support overall health as well as back health.
4. Prioritize Sleep and Recovery
Adequate sleep is important for overall health and recovery. Choose a comfortable sleeping position that does not increase your back or leg pain. If a particular position worsens your symptoms, adjust your position or discuss your symptoms with your healthcare provider.
5. Manage Stress
Chronic pain can affect mood, sleep, and daily functioning. Relaxation techniques, mindfulness, breathing exercises, and other stress-management strategies may help you cope with persistent pain.
When Should You See a Doctor for Sciatica?
You should speak with a healthcare provider if your back or leg pain is persistent, worsening, interfering with daily activities, or accompanied by numbness or weakness.
Seek urgent medical attention if back or leg pain occurs with new loss of bladder or bowel control, numbness around the groin or inner thighs, or significant or rapidly worsening weakness. These symptoms can indicate a serious condition requiring prompt evaluation.
