Sciatica: Symptoms, Causes & Treatment for Sciatic Nerve Pain

Sciatica is one of the most common causes of lower back pain that radiates down the leg. Many people describe it as a sharp, burning, or electric-like pain that starts in the lower back and travels through the buttock, thigh, or calf.

While some cases improve with rest and conservative treatment, sciatic pain can also become persistent and interfere with daily activities such as walking, sitting comfortably, or sleeping.

Sciatica is not considered a disease itself, but rather a group of symptoms caused by irritation or compression of a lumbar nerve root that forms part of the sciatic nerve.

In this article, you’ll learn what causes sciatica, the most common symptoms, when to see a specialist, and which treatment options may help relieve sciatic nerve pain.

Sciatica occurs when the sciatic nerve or the lumbar nerve roots connected to it become irritated or compressed.

The sciatic nerve begins in the lower spine and travels through the:

• Buttocks
• Hips
• Back of the legs
• Calves
• Feet

Because of this, pain can radiate from the lower back down into the leg.

In most cases, sciatica affects only one side of the body.

Common Causes of Sciatica
Sciatica can develop due to different conditions affecting the spine or nearby structures.

This is one of the most common causes of sciatica.

It occurs when part of a spinal disc presses against a nearby nerve root.

Symptoms may include:

• Pain radiating down the leg
• Tingling sensations
• Numbness
• Muscle weakness

Age-related wear and tear of the spine may lead to abnormal bone growth or narrowing around the nerves.

This can place pressure on the sciatic nerve.

Spinal stenosis is the narrowing of the spinal canal.

When this happens in the lower back, it may cause:

• Lower back pain
• Pain while walking
• Leg weakness
• Numbness or tingling

Less commonly, the piriformis muscle can irritate the path of the sciatic nerve and cause symptoms similar to sciatica.

This may result in buttock pain and discomfort radiating down the leg.

Several factors may increase the risk of developing sciatica, including:

• Diabetes
• Excess weight
• Sedentary lifestyle
• Poor posture
• Jobs involving heavy lifting
• Sitting for long periods of time

Symptoms vary depending on the degree of nerve irritation or compression.

This is the most characteristic symptom of sciatica.

The pain may feel like:

• Burning
• Electric shock sensations
• Sharp pain
• Constant aching
• Pressure or tightness

Pain usually begins in the lower back or buttock and travels down one leg.

Many patients experience:

• Pins and needles sensations
• Leg numbness
• Tingling
• Altered sensation in the leg or foot

More severe cases may cause difficulty:

• Walking
• Lifting the foot
• Maintaining balance
• Standing for long periods

Sciatica often worsens when:

• Sitting for extended periods
• Coughing
• Sneezing
• Making certain movements

In some patients, lower back pain may be mild or even absent, while leg pain becomes the main symptom.

Although some episodes improve within a few days, certain symptoms require medical evaluation.

You should see a specialist if:

• Pain lasts longer than one week
• Symptoms progressively worsen
• You experience leg weakness
• There is numbness or loss of sensation
• Pain interferes with walking
• You lose bladder or bowel control
• Symptoms begin after a fall or accident

Early medical care can help prevent complications and improve recovery.

Depending on the severity and cause of symptoms, different specialists may be involved in treatment.

Orthopedic specialists evaluate spinal conditions, disc herniations, and musculoskeletal problems related to lower back pain and sciatica.

When significant nerve compression or severe neurological symptoms are present, a neurosurgeon may recommend advanced treatment options or spine surgery.

Physical therapy helps improve mobility, strengthen muscles, and reduce pressure on the spine.

Pain management specialists may help patients experiencing chronic lower back pain or persistent sciatica symptoms.

Diagnosis usually includes:

• Medical history review
• Physical examination
• Neurological evaluation
• Muscle strength and reflex testing

Imaging studies may also be recommended, such as:

• X-rays
• MRI scans
• CT scans

These tests help identify herniated discs, nerve compression, or other spinal conditions.

Treatment depends on the cause of pain and severity of symptoms.

Some medications may help reduce:

• Inflammation
• Pain
• Muscle spasms

These should always be used under medical supervision.

Physical therapy may help:

• Improve posture
• Strengthen muscles
• Reduce nerve pressure
• Restore mobility

Many patients improve significantly with proper rehabilitation.

In some cases, specialists may recommend:

• Epidural steroid injections
• Interventional pain procedures
• Targeted pain management therapies

These treatments may help reduce inflammation and improve pain control.

Surgery is generally reserved for severe cases, especially when there is:

• Significant muscle weakness
• Loss of bladder or bowel control
• Severe nerve compression
• Persistent or disabling pain

In addition to medical treatment, certain measures may help reduce symptoms:

• Apply cold packs during the first 48 hours
• Use heat therapy afterward
• Avoid prolonged bed rest
• Stay moderately active
• Perform recommended stretches and exercises
• Maintain proper posture

Some patients also find complementary relief through therapies such as acupuncture or chiropractic care when guided by healthcare professionals.
