Sciatica That Won’t Go Away: Why Painkillers Often Don’t Work

Painkillers rarely resolve persistent sciatica because they mask the pain signal without addressing the structural problem causing it. When the sciatic nerve is compressed by a herniated disc, a misaligned vertebra, or spinal stenosis, no amount of medication corrects that underlying pressure.

If your sciatica keeps coming back, or never fully goes away, the pain is telling you that the root cause has not been treated.

In this blog post, we’ll cover the main causes of sciatica, why painkillers don’t work to completely treat sciatica, and sciatica treatments we regularly have success with in our San Diego, CA chiropractic office.

Why Painkillers Don’t Work for Sciatica

Sciatica is not a muscle ache or a soft tissue inflammation you can simply medicate away. It is a nerve compression problem.

The sciatic nerve, the longest nerve in your body, originates in the lower back and travels through the hips, buttocks, and down each leg. When something physically presses on that nerve, whether a bulging disc, a herniated disc, or a spinal misalignment, the pain, numbness, and tingling you feel are symptoms of that mechanical pressure.

Pain medications, including ibuprofen, acetaminophen, muscle relaxants, and even prescription opioids, work by blocking or blunting pain signals in the nervous system.

They do not decompress a disc.

They do not restore spinal alignment.

They do not reduce actual nerve pressure.

A 2012 systematic review published in BMJ found that existing evidence for the efficacy of drugs commonly prescribed for sciatica, including NSAIDs, corticosteroids, and opioids, is of low quality and does not clearly show favorable effects even compared to placebo.

UK medical guidelines now actively discourage the use of gabapentinoids, corticosteroids, benzodiazepines, and opioids for sciatica. A 2017 trial published in the New England Journal of Medicine found that pregabalin, a commonly prescribed nerve pain drug, did not significantly reduce leg pain from sciatica compared to placebo, while causing higher rates of dizziness, confusion, and sedation.

The medication carries real risk, with no reliable structural benefit.

At Intouch Chiropractic, when patients first come to us, many are already taking over-the-counter or prescription painkillers and muscle relaxants. They often tell us the medications take the edge off for a few hours, but the pain always returns. That is because medications don’t cure a biomechanical problem.

When the pill wears off, the compression on the nerve is still there.

“I have had chronic low back pain and sciatica for over 10 years. After trying regular chiro, massages, stretching etc for years, I luckily found Dr Tapia and Dr Young and their amazing team. This is the first time in years I have had sustained relief from my symptoms. My days are far more enjoyable and sleep is much better. I have learned so many other things from Dr Tapia that have drastically improved my over all health and well being. I highly recommend Intouch and wish I had found them sooner.” – Intouch Chiropractic Sciatica Treatment Review by Dave C.

What Is Actually Causing Your Persistent Sciatica

Persistent sciatica pain that has lasted weeks, months, or years, almost always has a clear structural cause that has not been fully corrected.

The most common underlying causes we see in our sciatica patients include:

• Herniated or bulging disc: The soft inner gel of a disc pushes outward and presses directly onto the sciatic nerve root in the lumbar spine, producing sharp, radiating pain from the lower back into the leg.
• Spinal stenosis: A narrowing of the spinal canal that places ongoing pressure on nerve roots, often causing pain that worsens with standing or walking.
• Degenerative disc disease: Disc height loss over time reduces the space through which nerve roots exit the spine, creating chronic irritation.
• Atlas misalignment: When the atlas, the top vertebra in the spine, shifts out of its normal position, the entire spine compensates by tilting and twisting. This compensation creates abnormal stress on discs, joints, and nerves all the way down into the lower back, including the sciatic nerve. This is one reason sciatica can be so difficult to treat when you only focus on the lower back.
• Piriformis irritation: The piriformis muscle in the buttock can tighten and irritate the sciatic nerve where it passes beneath or through it, mimicking disc-related sciatica.
• Chronic inflammation: Ongoing disc pressure and spinal misalignment restrict normal blood and nutrient flow to damaged areas, slowing the body’s natural healing process and keeping the nerve in a state of sustained irritation.

Recognizing Persistent Sciatica Symptoms

Sciatica does not always feel the same from person to person. The nerve covers a large area of the body, and where and how it is compressed affects the pattern of symptoms.

Common signs that your sciatica has not resolved include:

• Sharp, shooting, or electric pain that travels from the lower back through the buttock and down one leg
• Burning or aching pain along the back of the thigh or calf
• Numbness or tingling in the leg, foot, or toes
• Muscle weakness in the affected leg
• Pain that worsens when sitting for prolonged periods
• Symptoms that fluctuate but never fully disappear, even with rest or medication

If you have been experiencing any combination of these symptoms for more than four to six weeks, and pain medication provides only temporary relief, this is a strong signal that a structural problem has not been addressed. Continuing to medicate without identifying and correcting the underlying cause often leads to a longer recovery and a higher risk of the condition worsening over time.

Sciatica Treatment Options That Address the Root Cause

Effective sciatica treatment needs to do more than block pain signals. It needs to reduce the physical compression on the sciatic nerve and correct the structural problems maintaining that compression.

At Intouch Chiropractic in San Diego, we use a combination of non-surgical therapies designed to do exactly that.

NUCCA Chiropractic Care

NUCCA (National Upper Cervical Chiropractic Association) care is a highly precise, gentle approach that focuses on correcting misalignment of the atlas, the C1 vertebra at the top of the spine. When the atlas is out of position, the entire spine shifts to compensate, placing abnormal stress on discs, joints, and nerves all the way into the lower back.

By restoring proper alignment at the top of the spine, NUCCA care reduces that compensatory tension throughout the entire spinal column, including the nerve roots responsible for sciatica. NUCCA care is non-invasive, requires no forceful twisting or cracking, and is effective for patients who have not found lasting relief through traditional chiropractic or other conservative care.

DRX9000 Non-Surgical Spinal Decompression

Spinal decompression therapy uses a specialized motorized table to gently and precisely stretch the spine, creating negative pressure within the disc space. This decompression draws herniated or bulging disc material back toward the center of the disc, relieves direct pressure on the sciatic nerve, and restores proper fluid and nutrient flow to damaged discs to support healing. Research suggests that spinal decompression therapy can help patients avoid surgery in 75 to 85 percent of cases where surgical intervention was being considered.

For patients with chronic sciatica driven by disc compression, this is one of the most targeted, evidence-informed non-surgical treatments available.

Combining NUCCA and Spinal Decompression

Many of our patients with persistent sciatica benefit most from combining NUCCA care and DRX9000 spinal decompression, because these therapies target two distinct but deeply connected causes of chronic spinal pain.

• NUCCA corrects structural misalignment from the top of the spine down.
• Spinal decompression directly treats compressed and damaged discs.

When used together, these non-surgical therapies create a more complete and longer-lasting solution than either approach alone.

Low-Level Laser Therapy

We also use low-level laser therapy as a supportive treatment for patients with sciatica. Laser therapy targets damaged tissues, accelerates the body’s natural healing response, and helps reduce chronic inflammation around the sciatic nerve.

When combined with NUCCA care and spinal decompression, it supports faster tissue repair and helps maintain the relief achieved through structural correction.

When to Seek Care for Sciatica

Most sciatica cases improve with proper conservative care, but there are situations where you should seek professional evaluation promptly. See a provider right away if you experience:

• Sudden, severe pain in the lower back or leg following a fall, accident, or injury
• Loss of bladder or bowel control alongside back and leg pain (this requires emergency care)
• Progressive weakness in the leg that is getting worse, not better
• Sciatica symptoms that have persisted for more than six weeks without improvement despite conservative treatment
• Pain so severe it prevents normal daily activity and is not responding to any form of care

If your symptoms do not fall into those urgent categories but you have been managing with painkillers for weeks or months without resolution, that is the right time to seek a structural evaluation.

At Intouch Chiropractic, we take a thorough look at your spinal alignment and disc health to identify what is actually driving your symptoms so we can build a treatment plan designed to fix the problem, not just manage it.

Frequently Asked Questions About Sciatica

Why does my sciatica keep coming back even after it feels better?

Sciatica often returns because the underlying structural cause, such as a herniated disc or spinal misalignment, was never fully corrected. Pain management and rest can reduce symptoms temporarily, but if the nerve compression is still present, symptoms will return with activity, prolonged sitting, or a minor physical stress. Lasting relief requires identifying and treating the structural problem.

Are steroid injections a better option than painkillers for sciatica?

Epidural steroid injections can reduce inflammation around the sciatic nerve and provide short-term relief for some patients, which makes them more targeted than oral pain medication. However, injections do not correct disc herniations or spinal misalignments, and their benefit is typically temporary. Most spine specialists consider them a bridge to allow rehabilitation, not a long-term solution on their own.

How long does it take to see results with chiropractic care and spinal decompression for sciatica?

Many patients at Intouch Chiropractic report meaningful improvement within the first few weeks of a combined treatment plan. The full course of care depends on the severity of disc involvement and how long the condition has been present. Chronic sciatica that has persisted for months or years typically requires a longer, more comprehensive treatment plan than a recent onset.

Is NUCCA chiropractic care safe for sciatica?

Yes. NUCCA care is one of the gentlest forms of chiropractic treatment available. It does not involve forceful spinal manipulation, cracking, or twisting. The atlas correction is performed using a light, precise contact, making it appropriate for patients of all ages, including those who have not tolerated traditional chiropractic adjustments in the past.

Can I combine chiropractic care with physical therapy or other treatments for sciatica?

In many cases, yes. A well-coordinated care plan that addresses structural alignment, disc health, and muscular support can provide better outcomes than any single treatment alone. At Intouch Chiropractic, we evaluate each patient individually and build a treatment plan based on your specific diagnosis and history.
