How long does sciatica usually last?

Most episodes improve significantly within 6-12 weeks with conservative care. About 80-90% of patients avoid surgery. However, if you have severe weakness, progressive symptoms, or no improvement after 8-12 weeks of appropriate treatment, surgical options become more reasonable.

When should I get an MRI for sciatica?

MRI is most useful when it would change your treatment plan. I typically order imaging if: symptoms persist beyond 6-8 weeks despite conservative care, you have progressive weakness, there are red flags like bowel/bladder changes, or we're considering injections or surgery. Early MRI for mild symptoms often creates unnecessary anxiety without changing initial treatment.

Do epidural injections cure sciatica?

Injections reduce inflammation around the nerve, which can break the pain cycle and allow healing. They work best for disc herniations causing acute inflammation. Success rates vary—roughly 50-70% get meaningful relief. Some patients need only one injection; others need a series. Injections buy time for natural healing but don't fix structural problems like large disc fragments.

When does sciatica need surgery?

Surgery becomes reasonable when: conservative treatment fails after 8-12 weeks, you have progressive leg weakness, there's significant functional impairment affecting work or daily life, or you have cauda equina syndrome (bowel/bladder dysfunction—this is urgent). Surgery aims to remove pressure on the nerve, not cure all pain. Realistic expectations matter.

What's the success rate for sciatica surgery?

For properly selected patients with clear nerve compression on MRI matching their symptoms, microdiscectomy has 85-95% good-to-patient-specific outcomes for leg pain relief. Back pain is less predictable. Recovery typically takes 4-6 weeks for return to normal activity. Endoscopic techniques may allow recovery with similar outcomes.

Can sciatica come back after surgery?

Recurrence happens in about 5-10% of patients, usually within the first year. Risk factors include smoking, obesity, heavy lifting, and the size of the original herniation. We remove only the herniated portion of the disc, so there's remaining disc material that could potentially herniate again. Proper post-op activity modification reduces this risk.

Should I see a pain doctor or a spine surgeon first?

Either can be appropriate depending on your situation. Pain management excels at injection-based treatments and medication optimization. Spine surgeons evaluate the structural problem and determine if surgery might help. I often work collaboratively with pain specialists—they handle injections while I provide surgical consultation if conservative care fails.

What are the red flags I shouldn't ignore?

Seek urgent evaluation for: loss of bowel or bladder control, progressive leg weakness (foot drop, can't stand on toes/heels), numbness in the saddle area, fever with back pain, history of cancer, significant trauma, or pain that wakes you from sleep. These suggest more serious conditions requiring immediate assessment.

Does physical therapy actually help sciatica?

Yes, when done correctly. PT focuses on nerve gliding exercises, core stabilization, and posture correction. It won't shrink a herniated disc, but it can reduce nerve irritation and prevent recurrence. The key is finding a therapist experienced with spine conditions who understands the difference between helpful discomfort and harmful pain.

How soon can I return to work after sciatica surgery?

Desk work: typically 2-3 weeks. Light physical work: 4-6 weeks. Heavy lifting or labor: 8-12 weeks. Endoscopic approaches may allow faster return. The limiting factor is usually sitting tolerance and the need to avoid prolonged flexion while the surgical site heals. Most patients notice immediate leg pain improvement but need time for incision healing and strength recovery.

Will I need fusion surgery for sciatica?

Rarely. Most sciatica from disc herniation is treated with simple decompression (microdiscectomy or endoscopic discectomy)—no fusion needed. Fusion becomes necessary only if there's instability, significant spondylolisthesis, or recurrent herniations requiring extensive disc removal. For straightforward disc herniations, motion-preserving decompression is the standard approach.

How long should sciatica last before seeing a surgeon?

If leg pain persists after 8-12 weeks of consistent conservative care without meaningful improvement, a surgical consultation is reasonable. If you develop progressive weakness, such as foot drop or difficulty walking, seek evaluation sooner. Most sciatica episodes improve within 6-12 weeks without surgery.

Can sciatica be treated without surgery?

Yes. About 80-90% of sciatica cases resolve without surgery. Conservative treatment includes physical therapy, anti-inflammatory medications, activity modification, and sometimes epidural steroid injections. Surgery is reserved for cases where conservative care fails, weakness progresses, or red-flag symptoms appear.

Sciatica Treatment in Fort Wayne, IN

Sciatica is pain that travels from the low back or buttock down the leg, usually caused by a nerve being pinched in the lumbar spine — most often by a herniated disc. It can bring sharp pain, numbness, tingling, or weakness. Most sciatica improves without surgery.

Sciatica is nerve pain that travels from the low back or buttock into the leg, often caused by a herniated disc or spinal narrowing. Non-surgical care — including physical therapy, activity modification, and anti-inflammatory medications — is typically tried first. When leg pain, numbness, or weakness persists or worsens despite conservative treatment, a spine surgeon evaluation can help identify the specific problem and discuss available treatment options for sciatica in Fort Wayne.

When to get checked sooner

Seek prompt evaluation for progressive weakness in the leg or foot, new changes in bladder or bowel control, numbness in the saddle area (inner thighs, groin, or buttocks), fever with back pain, or rapidly worsening leg pain that limits walking. These may indicate a condition requiring urgent assessment.

Sciatica is leg pain caused by nerve compression in your lower back. Dr. Marc Greenberg treats sciatica for patients in Fort Wayne and across Northeast Indiana and Northwest Ohio, focusing on conservative care first and minimally invasive surgical options when needed. The pain travels—shooting down your leg, often past your knee, sometimes to your foot. You might feel sharp, electric jolts, burning, numbness, or tingling. Most episodes improve with conservative care within 6-12 weeks. When they don’t, or when weakness develops, there are effective minimally invasive surgical options including microdiscectomy and endoscopic spine surgery. Here’s what to look for, when imaging helps, and how we decide on treatment.

What Sciatica Feels Like

Sciatica has a signature pattern. The pain starts in your lower back or buttock and travels down the back of your thigh. It might stop at your knee, or it might continue to your calf, ankle, or foot. Some patients describe it as sharp and shooting—like an electric shock. Others feel burning or aching. Many notice numbness or tingling in specific areas of the leg or foot.

The distribution matters. L5 nerve root compression typically causes pain down the outside of your leg to the top of your foot and big toe. S1 compression goes down the back of your leg to the outside of your foot and small toes. Weakness follows the same pattern—L5 causes trouble lifting your foot (foot drop), while S1 affects pushing off your toes.

Sitting often makes it worse. Coughing, sneezing, or bearing down can trigger sharp pain. Some patients find relief standing or lying down. Others can’t find any comfortable position. The intensity varies—some people manage with modified activity, while others can barely walk.

Sciatica vs “Back Pain”

Sciatica (Nerve Pain)

Pain travels down leg past knee
Sharp, shooting, or burning quality
Numbness or tingling in specific areas
May cause leg weakness
Worse with sitting, coughing

Mechanical Back Pain

Pain stays in back or buttock
Aching, stiff, or sore quality
No numbness or tingling
No leg weakness
Worse with movement, better with rest

Key distinction: Sciatica travels. If your pain stays in your back, it’s not sciatica—even if it’s severe. The treatment approaches differ significantly. For a deeper look at disc-related nerve compression, see our herniated disc guide.

Common Causes

Herniated Disc (Most Common)

The disc between vertebrae develops a tear, and inner material pushes out, compressing the nerve root. This accounts for about 90% of sciatica cases in patients under 50. The herniation is often posterolateral—right where the nerve exits the spinal canal.

Typical presentation: Acute onset, often after lifting or twisting. Leg pain worse than back pain.

Spinal Stenosis

Narrowing of the spinal canal or nerve root canals from arthritis, thickened ligaments, or disc bulging. More common over age 60. The nerve compression is often positional—worse with standing or walking, better with sitting or leaning forward.

Typical presentation: Gradual onset. Leg pain with walking (neurogenic claudication). Relief with rest.

Spondylolisthesis

One vertebra slips forward on the one below, narrowing the nerve canal. Can be degenerative (from arthritis) or isthmic (from an old stress fracture). The slippage creates a kink in the nerve’s path.

Typical presentation: Positional pain. May have both back and leg symptoms.

Less Common Causes

Piriformis syndrome: Muscle in buttock compresses nerve (controversial diagnosis)
Tumor or infection: Rare but important to rule out with red flags
Scar tissue: After previous surgery

What I Look For on Exam

The physical exam helps confirm nerve involvement and identify which nerve root is affected. Here’s what I check:

Straight Leg Raise

I lift your leg while you’re lying down. If this reproduces your leg pain (not just back tightness) before 60 degrees, it suggests nerve root tension from a disc herniation. Highly specific for L5 or S1 radiculopathy.

What it means: Positive test increases likelihood of disc herniation by about 3-4x.

Strength Testing

I check specific muscle groups: ankle dorsiflexion (L5), great toe extension (L5), ankle plantarflexion (S1). Weakness in a specific pattern confirms which nerve is compressed and indicates more severe compression.

What it means: Weakness changes the urgency and treatment timeline.

Sensation Testing

Light touch and pinprick in specific dermatomes. L5 affects the top of the foot and big toe. S1 affects the outside of the foot and small toes. Numbness confirms nerve involvement but doesn’t predict surgical need.

What it means: Helps localize the problem and track changes over time.

Reflex Testing

Knee jerk (L4), ankle jerk (S1). Diminished or absent reflexes suggest nerve compression but can be normal with aging. Asymmetry between sides is more meaningful than absolute values.

What it means: Supports diagnosis but not required for treatment decisions.

Red Flags I’m Checking For

Cauda equina syndrome: Bowel/bladder dysfunction, saddle anesthesia—requires urgent surgery
Progressive weakness: Foot drop developing over days to weeks
Fever, night sweats, weight loss: Suggests infection or tumor
History of cancer: Metastatic disease can mimic sciatica
Significant trauma: Fracture needs to be ruled out

When Imaging Changes the Plan

I Order MRI When:

1Symptoms persist 6-8 weeks despite appropriate conservative care. At this point, we need to know what we’re dealing with to guide next steps.
2Progressive weakness develops. This suggests significant nerve compression that may need surgical decompression sooner rather than later.
3Red flags are present. Fever, cancer history, trauma, or cauda equina symptoms require immediate imaging.
4We’re considering injections or surgery. I need to see the structural problem to target treatment appropriately.

Why Not Image Everyone Immediately?

Because most sciatica improves with conservative care, and early MRI findings don’t predict who will get better. Studies show that 30-40% of people with no back pain have disc herniations on MRI. Finding a herniation doesn’t mean it’s causing your symptoms or that you need surgery.

Early imaging can also create nocebo effects—patients who see their MRI report describing “severe degeneration” or “large herniation” often have worse outcomes, even when the findings are common and not necessarily problematic. I prefer to treat the patient, not the image.

What You Can Try First

About 80-90% of sciatica episodes resolve with conservative treatment. The goal is to reduce nerve irritation, maintain function, and allow natural healing. Here’s the evidence-based approach:

Activity Modification

Stay active within pain limits. Bed rest beyond 1-2 days delays recovery. Avoid prolonged sitting, heavy lifting, and forward bending. Short walks are beneficial. Listen to your body—some discomfort is okay, but sharp pain means stop.

Timeline: Gradual improvement over 4-8 weeks typical.

Physical Therapy

Nerve gliding exercises, core stabilization, and posture training. A good PT understands the difference between therapeutic discomfort and harmful pain. McKenzie method (extension-based exercises) helps some patients; others need flexion-based approaches.

Timeline: 6-8 weeks of consistent therapy recommended.

Medications

NSAIDs (ibuprofen, naproxen) reduce inflammation. Neuropathic pain medications (gabapentin, pregabalin) can help nerve pain but have side effects. Muscle relaxants for spasm. Oral steroids sometimes used for acute flares. Opioids rarely appropriate beyond short-term use.

Timeline: Trial for 2-4 weeks; reassess if no benefit.

Ice and Heat

Ice for acute flares (first 48-72 hours). Heat for chronic symptoms and muscle spasm. Both provide temporary relief but don’t address the underlying problem. Use what feels better—there’s no wrong choice here.

Timeline: 15-20 minutes at a time, several times daily.

Realistic Expectations

Improvement is usually gradual, not sudden. You might have good days and bad days. The trend over weeks matters more than day-to-day fluctuations. If you’re not seeing meaningful improvement by 6-8 weeks, or if symptoms worsen, it’s time to reassess.

When Injections Help

Epidural steroid injections deliver anti-inflammatory medication directly to the inflamed nerve root. They don’t fix structural problems, but they can break the pain cycle and allow healing. Here’s when they make sense:

Best Candidates for Injection:

Acute disc herniation with significant leg pain (within 3-6 months of onset)
Clear nerve root compression on MRI matching clinical symptoms
Failed conservative care but not ready for surgery
Leg pain significantly worse than back pain

What Success Looks Like

Success rates vary: roughly 50-70% of patients get meaningful relief. Some need only one injection; others benefit from a series of 2-3 over several months. Relief may be temporary (weeks to months) or long-lasting. The goal is to reduce inflammation enough for natural healing to occur.

If you get significant relief that wears off, a repeat injection is reasonable. If you get no relief after 2-3 attempts, further injections are unlikely to help.

When Injections Don’t Help

Large disc fragments that mechanically compress the nerve often don’t respond well to injections—the problem is structural, not just inflammatory. Chronic symptoms (over 6-12 months) also respond less predictably. Stenosis from bone spurs has lower success rates than soft disc herniations.

Failed injections don’t mean you’re out of options—they help clarify that the problem is mechanical and may benefit from surgical decompression.

My Approach to Injections

When sciatica needs a surgeon

Surgery for sciatica aims to remove pressure on the nerve. It doesn’t cure all pain, and it doesn’t reverse nerve damage that’s already occurred. But for properly selected patients, it’s highly effective. If you’ve been told you need surgery and want an honest assessment, Dr. Greenberg offers independent second-opinion consultations that review all your options — surgical and non-surgical alike. Here are the decision points:

Urgent Indications

Cauda equina syndrome: Bowel/bladder dysfunction requires surgery within as clinically appropriate
Progressive weakness: Foot drop developing over days to weeks

Elective Indications

Failed conservative care: 8-12 weeks without meaningful improvement
Functional impairment: Can’t work, care for family, or maintain quality of life
Persistent severe pain: Despite appropriate treatment

Surgical Options

Microdiscectomy (Standard Approach)

Small incision (1-1.5 inches), microscope-assisted removal of herniated disc fragment. Outpatient or overnight stay. Success rate 85-95% for leg pain relief in properly selected patients. Recovery 4-6 weeks to normal activity.

Endoscopic Discectomy (Minimally Invasive)

Smaller incision (7-8mm), tubular approach with endoscopic visualization. Less tissue disruption, potentially recovery. Same goal as microdiscectomy—remove herniated disc material. Outpatient procedure. Not appropriate for all herniation types.

Laminectomy (For Stenosis)

Removes bone and ligament to decompress nerve roots. Used for spinal stenosis rather than disc herniation. Can be done minimally invasively. May be combined with fusion if instability present.

Realistic Outcomes

Surgery is excellent for relieving leg pain from nerve compression. It’s less predictable for back pain. Most patients notice immediate improvement in leg pain after surgery, though some numbness may persist. Weakness recovery depends on duration and severity—longstanding weakness may not fully resolve.

Recurrence rate is about 5-10%, usually within the first year. Risk factors include smoking, obesity, and heavy lifting. We remove only the herniated portion of the disc, so there’s remaining disc material that could potentially herniate again. Proper post-op activity modification reduces this risk.

Red Flags — Seek Urgent Care

These symptoms suggest serious conditions requiring immediate evaluation:

Loss of bowel or bladder control — Suggests cauda equina syndrome, requires emergency surgery
Progressive leg weakness — Foot drop developing over days, can’t stand on toes or heels
Saddle anesthesia — Numbness in the groin, buttocks, or inner thighs
Fever with back pain — May indicate spinal infection
History of cancer — Metastatic disease can cause similar symptoms
Significant trauma — Fall, accident, or injury preceding symptoms

If you experience any of these symptoms, go to the emergency room or call 911. Don’t wait for an appointment.
