Sciatica is a common condition that affects many people, especially those who sit for long periods of time or have a history of back problems. Sciatica is not a disease, but a symptom of an underlying problem that irritates or compresses the sciatic nerve.
The sciatic nerve is the longest and thickest nerve in the body, running from the lower back to the buttocks and down the back of each leg. It controls the muscles and sensations in the lower limbs.
When the sciatic nerve is pinched or inflamed, it can cause pain, numbness, tingling, weakness, or difficulty moving the affected leg. The pain can range from mild to severe, and can be constant or intermittent.
Some people may also experience lower back pain or hip pain. The pain may worsen with certain movements, such as bending, twisting, coughing, sneezing, or sitting for long periods. In this article we will explain What is sciatica and how can you treat sciatica?
What causes sciatica?
There are many possible causes of sciatica, but the most common ones are:
- Lumbar herniated disc: This occurs when the soft inner material of a disc in the lower spine bulges out through a tear in the outer layer and presses on a nearby nerve root. This can irritate or compress the sciatic nerve and cause sciatica.
- Lumbar spinal stenosis: This occurs when the spinal canal narrows due to aging, arthritis, or other factors and puts pressure on the nerve roots in the lower spine. This can also affect the sciatic nerve and cause sciatica.
- Spondylolisthesis: This occurs when one vertebra slips forward over another and causes misalignment of the spine. This can create a gap where a nerve root can exit and become pinched by the adjacent vertebra. This can also lead to sciatica.
- Piriformis syndrome: This occurs when the piriformis muscle, which is located deep in the buttock and helps rotate the hip, becomes tight or spasms and irritates or compresses the sciatic nerve that runs beneath it. This can cause sciatica-like symptoms in the buttock and leg.
- Other causes: There are some less common causes of sciatica, such as spinal tumors, infections, injuries, pregnancy, or diseases that affect the nerves.
How is sciatica diagnosed?
To diagnose sciatica, a doctor will ask about your medical history and symptoms and perform a physical examination. The doctor may check your reflexes, muscle strength, sensation, and posture. The doctor may also ask you to perform some movements that may trigger or worsen your pain.
The doctor may also order some tests to confirm the diagnosis and identify the underlying cause of your sciatica.
These tests may include:
- X-rays: These can show the alignment and structure of your spine and reveal any bone spurs, fractures, or arthritis that may be causing your sciatica.
- MRI: This can provide detailed images of your soft tissues and show any disc herniation, spinal stenosis, spondylolisthesis, tumors, infections, or inflammation that may be affecting your sciatic nerve.
- CT scan: This can also show detailed images of your bones and soft tissues and help detect any abnormalities that may be causing your sciatica.
- Electromyography (EMG): This can measure the electrical activity of your muscles and nerves and help determine if there is any nerve damage or compression that may be causing your sciatica.
How is sciatica treated?
The treatment of sciatica depends on the severity of your symptoms and the underlying cause of your condition. The main goals of treatment are to relieve pain, reduce inflammation, restore function, and prevent recurrence.
The most common treatments for sciatica include:
- Medications: These can help reduce pain and inflammation and improve your quality of life. Some common medications for sciatica include over-the-counter pain relievers (such as ibuprofen or naproxen), prescription anti-inflammatory drugs (such as corticosteroids), muscle relaxants (such as cyclobenzaprine), anticonvulsants (such as gabapentin), antidepressants (such as duloxetine), or opioids (such as tramadol).
- Physical therapy: This can help improve your posture, flexibility, strength, and mobility and prevent further injury to your spine and nerves. A physical therapist can teach you exercises that target your core muscles (such as abdominal and back muscles) that support your spine and reduce pressure on your sciatic nerve.
A physical therapist can also use techniques such as massage, heat therapy, cold therapy, ultrasound therapy, electrical stimulation therapy, or traction therapy to relieve pain and inflammation.
- Alternative therapies: These can help complement your medical treatment and provide additional relief from pain and stress. Some alternative therapies for sciatica include acupuncture (which involves inserting thin needles into specific points on your body to stimulate healing), chiropractic care (which involves manipulating your spine to improve alignment and function), yoga (which involves stretching and breathing exercises to enhance physical and mental well-being), massage therapy (which involves kneading and rubbing your muscles to improve blood flow and relaxation), or biofeedback (which involves using sensors to monitor your bodily responses such as heart rate, blood pressure, muscle tension, or brain waves and learning how to control them with relaxation techniques).
- Surgery: This is usually reserved for severe cases of sciatica that do not respond to conservative treatments or cause significant disability or neurological problems. Surgery aims to remove or repair the source of nerve compression or irritation such as a herniated disc, spinal stenosis, spondylolisthesis, tumor, infection, or injury. Some common surgical procedures for sciatica include microdiscectomy (which involves removing part of a herniated disc through a small incision), laminectomy (which involves removing part of a vertebra to create more space for the nerve roots), spinal fusion (which involves joining two or more vertebrae together with screws, rods, plates, or bone grafts to stabilize the spine), or artificial disc replacement (which involves replacing a damaged disc with an artificial one).
How can you prevent sciatica?
There are some steps you can take to prevent or reduce your risk of developing sciatica in the future.
- Maintaining a healthy weight: Being overweight or obese can put extra stress on your spine and increase your chances of developing disc degeneration, spinal stenosis, or spondylolisthesis that can cause sciatica.
- Exercising regularly: Staying physically active can help strengthen your core muscles that support your spine, improve your posture, and increase your flexibility and mobility. It can also help prevent stiffness and inflammation that can trigger sciatica. You should aim for at least 150 minutes of moderate-intensity aerobic exercise and two sessions of strength training per week. You should also avoid activities that involve excessive twisting, bending, or lifting that can strain your back and nerves.
- Practicing good ergonomics: You should pay attention to how you sit, stand, work, and sleep and make sure you adopt proper postures and positions that do not put undue pressure on your spine and nerves. You should also use ergonomic equipment such as chairs, desks, mattresses, pillows, or keyboards that support your natural curves and alignment of your spine. You should also take frequent breaks and change positions when you sit or stand for long periods to avoid stiffness and fatigue.
- Managing stress: Stress can cause muscle tension and inflammation that can aggravate your sciatic nerve. You should try to reduce stress levels by engaging in relaxing activities such as meditation, breathing exercises, listening to music, reading, or spending time with friends or family. You should also seek professional help if you suffer from anxiety, depression, or other mental health issues that affect your well-being.
Sciatica is a common condition that can cause pain, numbness, tingling, weakness, or difficulty moving the affected leg.
