Sciatica vs. Lower Back Pain — How to Tell the Difference and What to Do About It

Published by Empower Spine & Body | Powdersville, SC

Back pain and sciatica are two of the most common conditions we treat at Empower Spine & Body in Powdersville — and they are also two of the most commonly confused. Patients come in describing lower back pain that is actually sciatica. Others describe sciatica symptoms that turn out to be lumbar joint dysfunction. Understanding the difference matters because while both conditions involve the lower back, they have different causes, different presentations, and in some cases require different treatment approaches.

Here is how to tell them apart — and what each one means for your care.

What Is Lower Back Pain?

Lower back pain is pain that is localized to the lumbar region of the spine — the area between your bottom rib and your tailbone. It can feel like a dull ache, a sharp stab, a tightness, or a burning sensation. It may be constant or come and go. It may worsen with certain movements, prolonged sitting, or first thing in the morning.

Lower back pain has many structural causes — vertebral misalignment, disc degeneration, facet joint irritation, sacroiliac joint dysfunction, or pelvic imbalance. What these causes share is that the pain stays in the lower back. It does not travel.

If your pain is confined to the lumbar region and does not radiate into your hip, buttock, or leg — what you are most likely dealing with is lumbar back pain rather than sciatica.

What Is Sciatica?

Sciatica is not a diagnosis — it is a symptom. It describes pain that follows the path of the sciatic nerve — the longest nerve in the body — which originates from the lower lumbar spine, travels through the buttock, and runs down the back of the leg to the foot.

Sciatica occurs when the sciatic nerve or one of its contributing nerve roots is compressed or irritated — most commonly by a misaligned vertebra, a herniated disc, or pelvic dysfunction pressing on the nerve root where it exits the spine.

The defining characteristic of sciatica is radiation. The pain does not stay in the lower back — it travels. Patients describe it as shooting, burning, electric, or stabbing pain that moves from the lower back into the hip, buttock, and down one leg. Often accompanied by numbness, tingling, or muscle weakness in the affected leg or foot.

If your lower back pain travels — if it moves down into your hip, buttock, or leg — sciatica is almost certainly involved.

Key Differences at a Glance

Location of pain Lower back pain stays in the lumbar region. Sciatica travels from the lower back into the hip, buttock, and leg.

Type of sensation Lower back pain is commonly described as aching, tight, or sore. Sciatic pain is commonly described as shooting, burning, electric, or sharp — often with numbness or tingling.

Which side is affected Lower back pain can be central or bilateral. Sciatica is almost always one-sided — affecting either the left or right leg but rarely both simultaneously.

Effect of sitting Both worsen with prolonged sitting. Sciatica tends to worsen more dramatically with sitting because the seated position increases pressure on the lumbar discs and nerve roots.

Leg symptoms Lower back pain does not produce leg symptoms. Sciatica frequently does — including numbness, tingling, and weakness in the affected leg or foot.

Can You Have Both at the Same Time?

Yes — and most sciatica patients do. The nerve compression that causes sciatica almost always occurs in the context of lumbar spinal dysfunction. Most patients we see present with both local lower back pain and radiating sciatic symptoms simultaneously. The structural cause — misalignment, disc involvement, pelvic dysfunction — typically drives both.

How We Treat Both at Empower Spine & Body

Whether you are presenting with lower back pain, sciatica, or both — our approach begins the same way. A thorough consultation, comprehensive examination, and full spine digital X-rays taken in the standing, weight-bearing position. This gives us the objective structural picture we need to identify exactly what is driving your symptoms.

For lower back pain we correct the lumbar and pelvic misalignments identified through our Gonstead analysis — relieving joint stress, restoring proper mechanics, and addressing the postural and muscular factors contributing to the problem.

For sciatica we add spinal decompression therapy when disc involvement is present — gently creating negative intradiscal pressure to relieve nerve compression and promote healing — alongside specific Gonstead adjustments targeting the nerve root irritation.

Both conditions respond well to chiropractic care when the structural cause is properly identified and specifically addressed.
