Sciatica 101: Everything You Need to Know About That Nagging Nerve Pain

If you’ve ever had sciatica, you know it’s not just back pain. It’s a full-body experience that can hijack your days and steal your peace of mind. That sharp, burning, electric pain that shoots down your leg out of nowhere can make even the simplest things tying your shoes, driving to work, sitting through a meeting, standing long enough to cook dinner, or trying to sleep comfortably feel like uphill battles. The pain flares without warning, and suddenly everything revolves around avoiding that next jolt.

Over time, it’s not just your body that suffers. It’s missing out on family walks, workouts, social plans, or just feeling like yourself again. It’s the frustration of wanting to move freely but being reminded, over and over, that your body isn’t cooperating. And honestly, that wears you down physically, mentally, and emotionally.

At Thrive Health Systems, we see that every day. People come in tired, discouraged, and just ready for their lives to feel normal again. And we get it. Pain like that changes everything. But here’s the good news: it doesn’t have to stay that way.

We sat down with a few of our doctors who treat this stubborn condition every day and who have seen incredible turnarounds without drugs or surgery. They’re sharing what’s really going on inside the body when sciatica strikes, and how the right care can not only calm the pain but help your body truly heal so you can get back to doing the things you love without fear of that next painful flare.

Because you deserve more than temporary relief. You deserve your life back.

What Causes Sciatica?

Sciatica is more than just “back pain.” Thrive’s Dr. Grammer explains what sciatica actually is — how the sciatic nerve works, why it becomes irritated, and what really causes pain, burning, numbness, or tingling down the leg. He breaks down how disc degeneration, posture, and everyday stress can put pressure on the nerve and lead to major symptoms, even weakness or drop foot. If you’ve been dealing with persistent low back or leg pain, this explanation helps you understand the true root cause and where real relief begins.

Common structural causes (what we look for as chiropractors):

• Herniated or bulging discs
• Spinal misalignments (subluxations)
• Degenerative disc disease
• Spinal stenosis (narrowing of the spine)
• Poor posture and movement habits

Lifestyle and functional medicine factors:

• Chronic inflammation that irritates nerves
• Muscle weakness or imbalance from too much sitting
• Nutrient deficiencies that slow healing
• Metabolic issues that affect how your body repairs

Symptoms of Sciatica

Sciatica pain can feel different from person to person, but common symptoms include:

• Sharp, shooting pain down one leg
• Tingling, burning, or “pins and needles”
• Numbness or weakness in the leg or foot
• Pain that worsens when sitting, coughing, or sneezing

It is important to understand that sciatica is not the root problem. It is a symptom that points to an underlying issue.

Why Your Herniated Disc May Be Causing Sciatica: Dr. Grammer Explains

Dr. Grammer explains that if you have a herniated disc in your lower back, it’s often the main cause of sciatica. The L4-L5 and L5-S1 discs are most commonly involved, and when the disc material shifts outside its normal space, it can irritate the sciatic nerve. This pressure, along with caustic chemicals released from the disc, can cause sharp pain, tingling, numbness, or weakness down the leg — the hallmark symptoms of sciatica.

How Posture and Spinal Curvature Lead to Disc Degeneration (and Sciatica)

One of the most overlooked causes of sciatica is poor posture. We tend to think of posture as something cosmetic, but the truth is that it directly affects the health of your spine, especially the L4-L5 and L5-S1 discs in your lower back.

This is the area where your center of gravity lives, and it’s also where the natural curve of the lumbar spine begins. That curve isn’t optional, it’s essential. It acts like a built-in shock absorber every time you walk, bend, lift, or move through your day.

Dr. Grammer explains that when you start to lose this natural curvature, often from years of sitting, slouching, driving, or leaning over devices — the discs in your lower back take on stress they were never designed to handle. Over time, this added pressure leads to disc degeneration, making the L4-L5 disc the most common one to herniate.

A herniated disc in this area can easily irritate the sciatic nerve, triggering pain, numbness, tingling, or weakness down the leg.

How We Diagnose Sciatica at Thrive

Every patient is unique, so we start with a full evaluation. This includes:

• Doctor Consultation to review your health history and current concerns
• Comprehensive Exam to check posture, alignment, movement patterns, and nerve function
• Orthopedic and Neurological Testing to assess spinal and joint health
• Spinal Decompression Treatment to begin relieving pressure and improving mobility
• Review of Findings so you understand what is happening in your body and how we can help

Our goal is to uncover why your nerve is irritated so we can create the most effective plan to correct it.

How We Treat Sciatica

At Thrive, we use a combination of chiropractic care and functional medicine support to relieve pain and prevent it from coming back.

Chiropractic care may include:

• Gentle spinal adjustments to relieve nerve pressure
• Decompression therapy to reduce disc stress
• Functional movement exercises to restore strength and stability

Functional medicine support may include:

• Anti-inflammatory nutrition assessment and guidance
• Supplements that support nerve and muscle healing (like B vitamins, magnesium, and omega-3s)
• Stress management and lifestyle strategies to prevent flare-ups

Additional supportive therapies may include: Massage Therapy, Acupuncture, or Class IV Laser Therapy.

Why Waiting Makes Sciatica Worse (and What to Do Instead)

One of the biggest mistakes people make with sciatica is hoping it will “just go away.” Weeks turn into months, and before they know it, the pain, numbness, or tingling becomes a constant part of daily life. But as Dr. Grammer explains, the longer you ignore sciatica, the more damage can occur and the harder it becomes to treat.

He compares it to the old saying: “The best time to plant a tree was 20 years ago. The second-best time is today.”
If you’ve been dealing with sciatica for a while, the next best step is simply to start now.

Dr. Grammer emphasizes that putting off treatment increases the risk of becoming a surgical candidate or developing permanent nerve damage, something nobody wants. Early evaluation and targeted care can interrupt this cycle, reduce inflammation, restore function, and help the sciatic nerve heal before the issue becomes severe or irreversible.

What to Expect Moving Forward

Healing from sciatica is possible…and you don’t have to navigate the pain alone. Many people who come to us feel frustrated, limited, or worried that the discomfort will just keep coming back. We understand how much it can affect your sleep, your mood, your work, and even the simple things you love doing each day.

When sciatica is left untreated, the pain often returns, sometimes stronger and more disruptive than before. That’s why our approach is different. Instead of masking symptoms, we focus on discovering the true source of your pain, correcting it, and guiding your body back toward natural healing…without relying heavily on medications or invasive procedures.

At Thrive, your care may include:

• Gentle spinal adjustments to relieve nerve pressure

• Decompression therapy to reduce disc stress

• Functional movement exercises to restore strength and stability

Our goal is to help you feel supported, understood, and truly on the path to lasting relief — so you can get back to living your life with confidence and comfort.

When to Seek Immediate Help

While most cases of sciatica are not emergencies, you should seek urgent medical care if you experience:

• Sudden severe weakness in the leg or foot
• Loss of bladder or bowel control
• Extreme, worsening pain that you cannot manage
