Sciatica is a common condition that causes pain, numbness, and tingling that travels from the lower back through the buttocks and down the leg. At PA Pain & Spine Institute, we understand how disruptive these symptoms can be, and we focus on evidence‑based, non‑surgical approaches to help patients find meaningful relief.
What Is Sciatica?
Sciatica describes irritation or compression of the sciatic nerve, the largest nerve in the body. It typically leads to pain that radiates along the nerve pathway—from the lower spine into the leg.
Research shows that sciatica affects a significant portion of adults, with prevalence estimates ranging from 1%–5% in the general population.¹ In many cases, early, conservative management improves symptoms without the need for major surgery.
Sciatica Treatment Options
At PA Pain & Spine Institute, we tailor treatment to the cause of your pain, using options supported by clinical evidence.
1. Physical Therapy & Therapeutic Exercise
Targeted exercises help improve flexibility, strengthen supporting muscles, and reduce nerve irritation. A 2016 Cochrane review found that exercise therapy provides meaningful improvements in pain and function for patients with low back pain and sciatica.⁵
Examples of helpful exercises may include:
- Nerve‑gliding stretches
- Core stabilization work
- Gentle hamstring flexibility exercises
Your clinician will tailor a plan to your specific needs.
2. Pain Management Interventions
Interventional pain procedures can significantly reduce inflammation near the nerve.
- Epidural steroid injections and nerve root blocks are among the most common options.
- A randomized clinical trial published in Pain Medicine found that epidural injections provided significant short‑term pain relief compared with placebo in patients with sciatica.⁶
These treatments can be especially useful when conservative measures like therapy have not fully resolved the pain.
3. Regenerative Medicine Options
Regenerative treatments like platelet‑rich plasma (PRP) and stem cell therapies aim to support natural healing processes and reduce inflammation.
Although research in this area is evolving, early studies indicate that PRP injections may improve pain and function in disc‑related and nerve‑irritation conditions.⁷
Regenerative medicine is always considered in the context of individual patient anatomy and symptoms.
4. Minimally Invasive Procedures
Some patients benefit from procedures that relieve nerve compression without traditional surgery.
- Minimally Invasive Lumbar Decompression (MILD) reduces pressure in the spinal canal through tiny incisions, often as an outpatient procedure. Outcomes data published in Clinical Spine Surgery supports its safety and effectiveness for appropriate candidates.⁸
This option may be suitable for patients with spinal narrowing contributing to sciatica.

When to Seek Immediate Care
Contact your provider promptly if you experience:
- Sudden or increasing weakness in the leg
- Loss of bladder or bowel control
- Pain that progressively worsens
These may signal more serious neurologic involvement requiring urgent care.
Symptoms of Sciatica
Symptoms often include:
- Sharp, electric‑like pain in the lower back, buttock, or leg
- Tingling or “pins and needles” sensations
- Numbness or weakness in the leg or foot muscles
- Pain that worsens with sitting, prolonged standing, or bending
These symptoms vary in intensity, depending on the degree of nerve irritation.
Common Causes of Sciatica
Sciatica occurs when structures in the spine compress or irritate the sciatic nerve roots. Common causes include:
Disc Herniation
A herniated disc occurs when the soft center of a spinal disc bulges outward and presses on a nerve. Disc herniation is one of the leading causes of sciatic symptoms in adults under age 50.²
Spinal Stenosis
Spinal stenosis refers to narrowing of the spinal canal. This narrowing puts pressure on nerve roots and is a frequent contributor to sciatica in older adults.³
Degenerative Disc Disease
As discs age, they lose height and elasticity, which can lead to instability and nerve irritation.⁴
Other factors such as trauma, repetitive strain, poor posture, and sedentary lifestyle may also contribute.
