If you have shooting pain down the back of your leg, tingling in your foot, or burning along your hip and glute, you might be dealing with sciatica — or you might be dealing with something that looks like sciatica but isn’t. The right treatment depends entirely on figuring out which one you have.
What is sciatica?
Sciatica is a description of symptoms (pain radiating down the back or side of the leg, often with numbness or tingling), not a single condition. True sciatica refers to irritation of the sciatic nerve itself — usually from a disc issue, stenosis, or another spine-level problem. The sciatic nerve is the longest nerve in the body, running from the lower back down the back of the thigh and into the lower leg and foot. When it’s compressed or irritated anywhere along its path, you get the classic radiating pain pattern.
Is it really sciatica, or something else?
This is the most important question for choosing the right treatment. Sciatica-like symptoms can come from several different sources:
- True sciatica: from a disc bulge, herniation, or spinal stenosis irritating the nerve root in the lumbar spine.
- Piriformis syndrome: a tight piriformis muscle compresses the sciatic nerve as it passes through the hip. The symptoms can look identical to true sciatica, but the treatment is completely different.
- SI joint dysfunction: sacroiliac joint problems can refer pain into the back of the leg in a sciatica-like pattern.
- Glute medius or hamstring referral: tight or trigger-point-laden glutes and hamstrings can refer pain down the leg.
- Other nerve issues: peroneal nerve, femoral nerve, or other peripheral nerve issues can mimic sciatica.
A proper assessment tells you which one you’re dealing with before you spend months chasing the wrong fix.
What causes sciatica?
The most common causes of true sciatica are: disc bulge or herniation (most common in adults 30-50), spinal stenosis (more common with age), spondylolisthesis (slippage of one vertebra on another), and degenerative disc disease. Risk factors include prolonged sitting, heavy or repetitive lifting with poor form, weak core stabilization, and genetics. Trauma can be a trigger but most cases develop gradually.
How is sciatica treated at RXN?
Treatment depends entirely on what’s actually causing the symptoms. For disc-related true sciatica, we use:
- Targeted spinal work and decompression-style adjustments to take pressure off the irritated nerve
- Graduated loading to calm the nerve and restore tolerance to movement
- Specific strengthening of the deep core, glutes, and posterior chain
- Patient education on what aggravates and what helps
For piriformis-related symptoms, we focus on:
- Soft-tissue release of the piriformis, deep external rotators, and surrounding muscles
- Glute strengthening (the piriformis often tightens because the glutes aren’t doing their job)
- Movement re-education to restore normal hip mechanics
- Stretching and mobility work for the hip and pelvis
How long does it take to recover from sciatica?
Highly variable. Some patients feel real relief in 1-2 weeks; others need 6-8 weeks of consistent work. The honest answer depends on what’s causing it and how long it’s been there. Acute disc-related sciatica can resolve relatively quickly with the right care; chronic cases with long-standing structural issues may need months. We’ll give you a realistic timeline after the assessment.
Do I need an MRI for sciatica?
Most cases of sciatica don’t require imaging. If conservative care is working and you’re improving steadily, imaging usually doesn’t change the plan. We recommend MRI in specific scenarios: progressive neurological symptoms (weakness, numbness that’s spreading), no improvement after 6-8 weeks of appropriate care, or red-flag symptoms (bladder/bowel changes, saddle anesthesia). If we think you need imaging, we’ll tell you and coordinate with a physician.
Will sciatica come back?
The honest answer: it can, especially if the underlying movement and strength deficits aren’t addressed. The most effective prevention is building hip mobility, core strength, and proper lifting and movement patterns — not just resolving the current episode and hoping it doesn’t recur. We build maintenance recommendations into every discharge plan to minimize the chance of recurrence.
