What Is Sciatica?

Causes, Symptoms, and Treatment Options

Sciatica is one of the most common causes of leg pain... but it's a symptom, not a diagnosis. Here's what you need to know. 

Many people use the word sciatica as if it were a diagnosis but it's more accurately a symptom pattern. Sciatica refers to pain, numbness, or tingling that radiates along the path of the sciatic nerve, which runs from your lower spine through your buttocks and down each leg.

When this nerve becomes irritated or compressed, the results can be debilitating. Understanding the underlying cause is the key to finding lasting relief.

Common Symptoms of Sciatica

Symptoms typically affect one side of the body and can range from a dull ache to a sharp, electric sensation.

•      Pain that radiates down one leg

•      Burning or electric shock sensations

•      Numbness or tingling in the leg or foot

•      Weakness while walking or standing

•      Pain that worsens with prolonged sitting or bending forward

What Causes Sciatica?

Several underlying conditions can lead to sciatic nerve irritation. Identifying the root cause is essential for effective treatment.

Herniated or Bulging Discs	One of the most frequent culprits is a disc pressing against a nerve root in the lumbar spine can trigger classic sciatica symptoms.
Spinal Stenosis	Narrowing of the spinal canal puts pressure on the nerves that travel through it, creating pain and cramping that radiates into the legs.
SI Joint Dysfunction	Inflammation of the sacroiliac joint can mimic true sciatic nerve pain, causing referred discomfort into the buttock and leg.
Degenerative Changes	Arthritis and disc degeneration that develop over time may progressively narrow the spaces around nerve roots, contributing to ongoing irritation.

Treatment Options

The right treatment depends on the severity of your symptoms and the underlying cause. A specialist will typically begin with conservative approaches and progress to interventional options if needed.

•      Physical therapy

•      Anti-inflammatory medications

•      Activity modification

•      Epidural steroid injections

•      Nerve-targeted treatments

•      Minimally invasive procedures

⚠ When to Seek Immediate Care: Progressive leg weakness, worsening numbness, or any changes in bowel or bladder control are warning signs that require prompt medical evaluation. Do not wait to see if these symptoms resolve on their own.

Frequently Asked Questions

Can sciatica go away on its own?

• Mild cases sometimes improve with rest and time, but persistent or worsening symptoms should always be professionally evaluated to rule out a more serious underlying cause.

Can SI joint pain cause sciatica symptoms?

• Yes. SI joint dysfunction can produce referred pain into the buttock and leg that closely resembles classic sciatica — which is why an accurate diagnosis matters before starting treatment.

What kind of doctor treats sciatica?

• A pain management specialist is well-positioned to evaluate nerve pain, identify the source of compression, and tailor a treatment plan to your specific condition.

Living with leg or back pain?

A thorough evaluation can identify the source of your pain and open the door to effective, targeted treatment. You don't have to manage sciatica alone.
