Most people can recognize the difference between a “tweak” in the back and pain that starts running the day. If you’re timing car rides around how long you can sit, cutting walks short because your leg starts burning or cramping, or waking up at night to reposition, it’s reasonable to wonder whether something structural is going on—and whether surgery is ever the right answer.
This article explains the most common reasons lower back pain becomes persistent, how a spine specialist confirms what’s actually causing your symptoms, and the surgical options that may be considered when appropriate non-surgical care hasn’t brought meaningful relief. If you are comparing surgeons and looking for the best spine surgeon in Los Angeles, the most helpful consultation is the one that gives you clarity: what the diagnosis is, why it matches your symptoms, and what outcomes are realistic with (and without) surgery.
Why Lower Back Pain Can Become Persistent
Your lumbar spine is built to move and to carry load. Discs cushion the vertebrae, small joints guide motion, and nerves travel through tight spaces on their way to the legs. Over time—or after an injury—those parts can become irritated, worn down, or crowded.
Many episodes of low back pain improve with time, activity modification, physical therapy, and anti-inflammatory strategies. Surgery tends to enter the conversation when there is a clear structural issue that can be corrected (for example, a nerve that is consistently compressed), or when instability is causing painful motion that doesn’t respond to non-surgical care.
If you’re still in the “what could this be?” stage, it can help to review the broader list of spine conditions that commonly show up on imaging and how they relate to everyday symptoms like standing intolerance, leg pain, or numbness.
Common Causes Behind Ongoing Lower Back Pain
“Lower back pain” is a symptom—not a diagnosis. The best treatment plan (surgical or not) depends on identifying the pain generator and whether nerves are involved.
Degenerative Disc Disease
Discs naturally lose water content and flexibility with age. In some people, that process causes disc height loss, small tears in the outer disc, and inflammation that can create localized low back pain. Degeneration can also contribute to narrowing around nerves, which can lead to sciatica symptoms down the leg.
Herniated Disc
A herniated disc happens when disc material bulges or protrudes and irritates a nearby nerve root. This often causes leg-dominant symptoms: sharp or electric pain down the buttock and leg, tingling, numbness, or weakness. Many herniations improve without surgery, but surgery may be considered when nerve pain is severe, prolonged, or paired with objective neurologic weakness.
Spinal Stenosis (Narrowing) and Pinched Nerves
Stenosis refers to narrowing of the spinal canal or the side openings where nerves exit. It’s commonly related to arthritis changes, thickened ligaments, disc bulges, or bone spurs. People often describe aching or heaviness in the legs with standing and walking that improves with sitting or leaning forward. For a deeper explanation of symptoms and patterns, see spinal stenosis.
Strain, Fracture, or Injury-Related Instability
Muscle strains are common and typically improve. But pain that persists after a fall, car accident, or sports injury may signal something deeper—such as a fracture, a disc injury, or instability (painful abnormal movement between vertebrae). The key is determining whether the primary driver is soft tissue, bone, disc, joints, or nerve compression.
How a Spine Specialist Diagnoses the Problem Before Recommending Surgery
A careful diagnosis is the difference between a targeted, helpful procedure and surgery that doesn’t address the real issue. Imaging findings also need context: many people have disc bulges or arthritis on MRI and feel fine.
A typical spine evaluation includes:
- Symptom mapping (back-only pain vs. leg-dominant pain, what positions worsen it, and what brings relief)
- Neurologic exam (strength, sensation, reflexes, balance, and gait)
- Imaging such as X-rays (alignment/instability), MRI (nerves, discs, soft tissues), or CT (bone detail) when appropriate
In some cases, your specialist may discuss diagnostic or therapeutic injections to help confirm which level or structure is responsible for symptoms before considering an operation.
Surgical Options for Lower Back Pain (and What Each One Is Designed to Fix)
Surgery is not one-size-fits-all. A useful way to think about spine procedures is by their main goal: decompress a nerve, remove a specific disc problem, preserve motion when appropriate, or stabilize a painful/unstable segment.

Spinal Decompression (Creating Space for Pinched Nerves)
When symptoms are driven by nerve compression—often felt as sciatica, numbness, or weakness—decompression procedures remove small amounts of bone, ligament, or disc material to open space around the nerve. The aim is to reduce nerve irritation and improve function (for example, walking tolerance).
Decompression can be performed in different ways depending on where the narrowing is occurring. Two common lumbar options include:
- Laminotomy, which removes a small portion of the lamina to relieve pressure while preserving as much normal anatomy as possible. Learn more about lumbar laminotomy.
- Foraminotomy, which enlarges the opening where a nerve exits the spine when that area is narrowed by bone spurs or disc material. Learn more about lumbar foraminotomy.
These procedures fall under the broader category of spinal decompression. Your imaging and exam help determine whether decompression is needed centrally, on one side, or at multiple levels.
Discectomy/Microdiscectomy (Removing the Part of a Herniated Disc Touching the Nerve)
When a herniated disc is the main source of leg pain, a discectomy removes the protruding disc fragment that is compressing or inflaming the nerve. The intent is to relieve nerve symptoms—not to “erase” every age-related change on imaging. This option is most often discussed when leg pain dominates and conservative treatment hasn’t been enough.
Disc Replacement (Motion Preservation in Selected Patients)
For certain disc-related pain patterns and carefully selected anatomy, disc replacement may be an option that preserves motion at the treated level. Candidacy depends on factors such as the number of discs involved, the condition of surrounding facet joints, overall alignment, and the presence or absence of instability or significant deformity.
Spinal Fusion (Stabilizing Painful Motion or Instability)
Fusion is designed to stop painful movement by encouraging two (or more) vertebrae to heal together. It may be considered for certain fractures, significant instability (including some forms of spondylolisthesis), deformity, or when decompression alone would leave the spine too unstable.
Fusion can be done using different approaches depending on the region and diagnosis. For example, in the neck a common approach is spinal fusion surgery (ACDF). In the lumbar spine, the technique varies by anatomy and goals. In a thorough consultation, your surgeon should explain why fusion is being recommended, what alternatives exist, and how fusion may affect mobility and adjacent segments over time.
Minimally Invasive Spine Surgery: What It Changes (and What It Doesn’t)
Many decompression procedures—and select stabilization surgeries—can be performed using minimally invasive approaches that reduce muscle disruption. For the right patient and the right diagnosis, that may mean less early postoperative pain and a faster return to basic activities. But minimally invasive techniques are tools, not a guarantee; what matters most is choosing an approach that safely addresses the underlying problem.
To understand where these techniques may fit, see minimally invasive spine surgery.
When to Seek a Spine Evaluation (and When to Seek Urgent Care)
A spine evaluation is worth considering when back pain is persistent and function-limiting, especially if symptoms suggest nerve involvement. Common reasons patients schedule a consultation include:
- Pain lasting several weeks (or longer) despite appropriate conservative care
- Leg pain, numbness, or tingling that suggests nerve irritation
- New or worsening weakness, foot drop, or symptoms that are progressing
- Difficulty walking or standing that improves with sitting or leaning forward
Seek urgent evaluation if you develop new bowel or bladder changes, numbness in the groin/saddle area, or rapidly worsening weakness, as these can be signs of a more serious nerve problem.
