Low Back Pain

What Is Low Back Pain?

Low back pain is pain, stiffness, soreness, or discomfort affecting the lumbar spine between the rib cage and pelvis. It may originate from the spinal muscles, discs, facet joints, vertebrae, ligaments, nerve roots, or other nearby structures.

Lower back pain may develop suddenly after lifting, twisting, falling, or another injury. It may also develop gradually because of disc degeneration, arthritis, spinal stenosis, nerve compression, instability, or repetitive strain.

Some cases remain limited to the lower back. Others cause pain, numbness, tingling, or weakness that travels into the buttock, hip, thigh, calf, or foot. Radiating symptoms may indicate lumbar radiculopathy or sciatica caused by irritation or compression of a spinal nerve.

De Novo Brain & Spine evaluates adults with persistent or severe low back pain in Stockbridge, Georgia, particularly when symptoms suggest disc disease, nerve compression, spinal stenosis, instability, fracture, deformity, or another structural lumbar spine condition.

Common Signs and Symptoms

Low back pain symptoms depend on the underlying cause, location of irritation, and whether spinal nerves are involved.

Common signs and symptoms may include:

• Aching, sharp, burning, or stabbing pain in the lower back
• Back stiffness or reduced range of motion
• Pain that worsens with bending, lifting, twisting, standing, or walking
• Pain that improves with rest, position change, or sitting in some cases
• Pain that travels into the buttock, hip, thigh, calf, or foot
• Sciatica, meaning nerve pain that travels down the leg
• Numbness, tingling, or pins-and-needles sensation in the leg or foot
• Weakness in the leg, ankle, or foot
• Foot drop or difficulty lifting the front of the foot in selected cases
• Muscle spasms in the lower back
• Difficulty standing upright or walking normally
• Pain that worsens with extension or arching of the back in some facet or stenosis-related conditions
• Symptoms that worsen with walking and improve with sitting or bending forward, which may occur with lumbar spinal stenosis

Seek urgent medical evaluation for low back pain with progressive weakness, numbness in the groin or saddle area, new bowel or bladder problems, fever, unexplained weight loss, history of cancer, severe pain after trauma, or pain with worsening neurological symptoms. Seek emergency medical care or call 911 for sudden leg weakness, loss of bowel or bladder control, or symptoms concerning for cauda equina syndrome.

When Low Back Pain May Be Nerve-Related

Low back pain may involve a spinal nerve when pain travels from the lower back into the buttock, hip, thigh, calf, ankle, or foot. Nerve-related symptoms may include burning pain, electric-like pain, numbness, tingling, reduced reflexes, muscle weakness, or foot drop.

Pain that remains mainly in the lower back may be related to muscles, spinal discs, facet joints, vertebral endplates, arthritis, or spinal instability. However, symptoms alone cannot always identify the exact source.

A neurological examination and lumbar spine imaging may be recommended when symptoms are persistent, severe, progressive, associated with trauma, or accompanied by numbness or weakness.

Understanding Low Back Pain

Low back pain can have many possible causes and may affect people differently. Some cases are related to muscles or other soft tissues, while others may involve spinal discs, joints, bones, or nerves.

Because similar symptoms can come from different conditions, identifying the source of low back pain usually involves reviewing a person’s symptoms, medical history, physical examination, and imaging when appropriate. Treatment depends on the underlying cause and the individual patient’s needs.

What Causes This Condition?

Low back pain can have many causes. Some are related to muscles and soft tissues, while others involve the discs, joints, nerves, bones, or stability of the lumbar spine.

Possible causes and related conditions may include:

• Lumbar muscle strain or ligament sprain
• Myofascial pain involving irritated muscles and soft tissues
• Herniated disc, when disc material irritates or compresses a nerve root
• Bulging disc
• Degenerative disc disease, involving wear or breakdown of spinal discs
• Discogenic pain, meaning pain thought to arise from the intervertebral disc
• Lumbar radiculopathy, or nerve root irritation in the lower back
• Sciatica, a common term for nerve pain traveling down the leg
• Lumbar spinal stenosis, which is narrowing around the spinal canal or nerve roots
• Neurogenic claudication, leg pain, heaviness, or weakness with walking caused by lumbar spinal stenosis
• Facet joint disease, involving the small joints in the back of the spine
• Spondylolisthesis, when one vertebra slips forward relative to another
• Spondylosis, or arthritis-related degenerative change in the spine
• Spinal instability
• Sacroiliac joint dysfunction or SI joint pain
• Vertebral compression fracture
• Osteoporotic spinal fracture
• Traumatic spinal fracture
• Scoliosis, kyphosis, infection, inflammatory disease, or spinal tumor in selected cases

These causes and risk factors do not mean every patient with low back pain has a serious spine condition. Treatment planning depends on symptoms, examination findings, imaging results when needed, neurological function, injury history, and overall health.

How Is Low Back Pain Diagnosed?

Low back pain is diagnosed through medical history, physical examination, neurological examination, and imaging or additional testing when appropriate. The goal is to determine whether the pain is muscular, joint-related, disc-related, nerve-related, fracture-related, instability-related, or caused by another condition.

Common diagnostic steps may include:

• Medical history and symptom review to understand pain location, duration, triggers, injury history, leg symptoms, weakness, numbness, prior treatment, and red-flag symptoms
• Physical examination to evaluate posture, range of motion, tenderness, muscle spasm, walking pattern, and painful movement
• Neurological examination to assess strength, sensation, reflexes, coordination, gait, balance, and signs of nerve root involvement
• Straight leg raise or other nerve tension testing when lumbar radiculopathy or sciatica is suspected
• X-rays of the lumbar spine to evaluate alignment, arthritis, disc space narrowing, fracture, deformity, or degenerative change
• Flexion-extension X-rays in selected cases to assess abnormal motion or spinal instability
• MRI of the lumbar spine when nerve compression, herniated disc, spinal stenosis, infection, tumor, fracture, or significant neurological symptoms are suspected
• CT scan of the lumbar spine when bone detail, fracture, or surgical planning requires further evaluation
• CT myelogram in selected cases when MRI is not possible or when additional detail around the spinal canal and nerve roots is needed
• Electromyography and nerve conduction studies, also called EMG/NCS, when symptoms may involve lumbar radiculopathy, peripheral neuropathy, peroneal neuropathy, or another nerve disorder
• Blood tests in selected cases when infection, inflammatory disease, cancer-related concern, or another medical condition is suspected
• Diagnostic injections in selected cases when the pain source may involve the facet joints, sacroiliac joint, or nerve root

The goal of diagnosis is to identify the likely pain generator, determine whether nerve compression or spinal instability is present, and decide whether conservative care, pain management, injections, or surgical evaluation may be appropriate.

Treatment Options

Low back pain treatment depends on the cause, severity, duration, neurological examination, imaging findings, prior treatment, activity limitations, and overall health. Many patients begin with non-surgical care when there is no progressive neurological deficit, fracture, infection, tumor, cauda equina syndrome, or other urgent concern.

Treatment options may include:

• Activity modification to reduce movements, positions, or lifting that worsen symptoms
• Physical therapy to improve core strength, flexibility, posture, walking mechanics, and lumbar spine stability
• Home exercise and stretching when recommended by a clinician or therapist
• Heat, ice, or other comfort measures for short-term symptom relief
• Anti-inflammatory medication, acetaminophen, muscle relaxants, or nerve pain medication when medically appropriate
• Weight management and conditioning when these factors are relevant to spine stress and overall health
• Treatment of posture, ergonomic, or activity-related contributors
• Lumbar epidural steroid injection in selected cases involving lumbar radiculopathy, sciatica, or nerve irritation
• Facet joint injection, medial branch block, or radiofrequency ablation in selected cases when facet-mediated low back pain is suspected
• Sacroiliac joint injection or SI joint treatment in selected cases when the sacroiliac joint is thought to be a pain source
• Basivertebral nerve ablation in selected patients with vertebrogenic low back pain and appropriate MRI findings
• Spinal cord stimulation in selected patients with chronic neuropathic pain or failed back surgery syndrome after specialist evaluation
• Microdiscectomy in selected cases involving lumbar disc herniation with nerve compression and persistent or progressive leg symptoms
• Lumbar laminectomy or decompression in selected cases involving spinal stenosis or nerve compression
• Lumbar fusion, such as transforaminal lumbar interbody fusion, lateral interbody fusion, or anterior lumbar interbody fusion, in selected cases involving instability, deformity, spondylolisthesis, or certain recurrent spine conditions
• Vertebral fracture treatment in selected compression fractures or traumatic fractures
• Rehabilitation and follow-up care to support strength, mobility, function, and symptom monitoring

Surgery is not appropriate for every patient with low back pain. Neurosurgical treatment may be considered when low back pain is associated with lumbar radiculopathy, spinal stenosis, spondylolisthesis, spinal instability, fracture, tumor, progressive neurological symptoms, or structural compression that has not improved with appropriate non-surgical care.

Frequently Asked Questions

How long should I try physical therapy or medication before seeing a specialist for low back pain?

Most patients try activity changes, physical therapy, and medication for several weeks before a specialist evaluation is needed. If pain isn’t improving in that time, if it’s getting worse, or if it starts moving into the leg with numbness or weakness, that’s a signal to move up to a spine specialist rather than continuing the same home routine. Sudden red-flag symptoms skip this timeline entirely and need same-day evaluation.

What’s the difference between low back pain and sciatica?

Low back pain generally stays in the lower back. Sciatica is a specific pattern where pain, numbness, or tingling travels from the lower back down through the buttock and leg, usually because a nerve root is being irritated or compressed. Not everyone with low back pain has sciatica, and the distinction matters for treatment. Sciatica often points toward a herniated disc or spinal stenosis as the underlying cause, while pain that stays local is more often muscular or joint-related.

Does low back pain always mean I’ll need surgery?

No. Most people with low back pain improve with non-surgical care such as physical therapy, activity modification, and medication. Surgery is typically considered when there’s confirmed nerve compression, spinal instability, a fracture, or progressive weakness that hasn’t responded to conservative treatment, not simply because pain has lasted a long time.

When is low back pain a medical emergency?

Low back pain becomes an emergency when it comes with new bowel or bladder problems, numbness in the groin or saddle area, or sudden leg weakness. These can be signs of cauda equina syndrome, which needs immediate emergency care, not a scheduled appointment. Fever, unexplained weight loss, or severe pain after a trauma also warrant urgent evaluation rather than a wait-and-see approach.

What happens at a first visit for low back pain evaluation?

A first visit typically includes a review of symptoms and history, a physical and neurological exam to check strength, sensation, and reflexes, and a discussion of whether imaging is needed. Many patients don’t need an MRI on day one. It’s ordered when the exam or symptom pattern suggests nerve involvement, instability, or another finding that would change the treatment plan.
