Sciatica: Causes, Symptoms, Types, Diagnosis and Treatments

Sciatica, a common type of pain affecting the sciatic nerve, can cause debilitating discomfort, typically in one side of the body. This nerve extends from your lower back down through your hips, buttocks, and down each leg, making it the longest nerve in the body. Symptoms often surface when this nerve is pinched or pressured, frequently due to a herniated disk, spinal stenosis, or a bone spur. This article aims to provide an understanding of the causes, symptoms, types, and treatment options for sciatica, helping those affected navigate their condition with knowledge and confidence.

What is sciatica?

Sciatica, also known as lumbar radiculopathy, is a type of pain that radiates from the lower back and travels down one or both legs. It is caused by irritation or compression of the sciatic nerve, which branches off from the spinal cord in the lower back and runs through the buttocks and down into each leg. The pain can range from mild to severe and can be accompanied by other symptoms such as numbness, tingling, or weakness in the affected leg.

Sciatica can be caused by a variety of factors, including:

  • Herniated or slipped disk: When the soft inner material of a spinal disk protrudes through the tough outer layer. It can press on the sciatic nerve, causing irritation and inflammation.
  • Spinal stenosis: This is a narrowing of the space around your spinal cord that puts pressure on the sciatic nerve.
  • Degenerative disc disease: As we age, our spinal discs can lose their cushioning and become brittle. Leading to herniated disks or bone spurs that irritate the sciatic nerve.
  • Piriformis syndrome: The piriformis muscle in the buttocks runs over the sciatic nerve. If this muscle becomes tight or spasms, it can put pressure on the nerve.


The most common symptom of sciatica is pain that radiates from the lower back down one leg. The pain can range from a mild ache to a sharp, shooting sensation and may worsen with prolonged sitting or standing. Other symptoms may include:

  • Numbness or tingling in the affected leg
  • Weakness in the affected leg
  • Burning or electric shock-like sensations down the leg
  • Difficulty controlling your bowels or bladder (in severe cases)
  • Constant pain in one side of the buttocks
  • Pain that intensifies when coughing or sneezing

These symptoms can be intermittent or constant and can vary in intensity. It is crucial to seek medical attention if the pain persists or worsens over time. Or if it is accompanied by sudden, severe symptoms or loss of function in your legs.


Sciatica is typically classified into two types: acute and chronic. Acute sciatica refers to pain that lasts for a short period, usually less than six weeks. This type of sciatica is often caused by a specific event, such as an injury or trauma. Chronic sciatica is pain that lasts longer than six weeks and is usually caused by an underlying medical condition, such as spinal stenosis or degenerative disc disease.

To diagnose sciatica, your doctor will perform a physical exam and review your medical history. They may also order imaging tests such as X-rays, magnetic resonance imaging (MRI), or computed tomography (CT) scans to rule out other conditions and confirm the cause of your pain. In some cases, a nerve conduction study may also used to measure the electrical impulses in your nerves.


Treatment options for sciatica will vary depending on the underlying cause and severity of symptoms. Some common treatments include:

  • Pain relievers: Over-the-counter or prescription medications may be used to help manage pain and inflammation.
  • Physical therapy: Exercises and stretches can help improve flexibility, strength, and mobility in the affected area.
  • Injections: Steroid injections into the spine can provide temporary relief from sciatica pain.
  • Surgery: In severe cases where conservative treatments do not provide relief. Surgery may be recommended to alleviate pressure on the sciatic nerve.

It is essential to work closely with your healthcare provider to determine the best course of treatment for your specific case. In many cases, a combination of treatments may be necessary for optimal results.
