Which Nerve Is Causing Your Sciatica? (L4, L5 or S1 Explained + 3-Step Fix)

If your pain shoots from your low back down the back of your thigh, into your calf or foot, or even into the front of your thigh or shin, those are not random pain patterns. Each one points to a specific nerve root being irritated, most commonly by a disc issue in your lower back. In this episode, I’ll show you how to identify which nerve root is involved in your sciatica and walk you through a simple 3-step routine to reduce disc pressure, calm the nerve, and start getting relief at home. Instead of chasing symptoms in your leg with random stretches, you’ll learn how to address the problem at the source, right in your lower back. In this video, you’ll learn: 🔷 The difference between L4, L5, and S1 nerve root pain patterns 🔷 Why sciatica pain in different parts of the leg often comes from the same disc 🔷 How to unload the spine to reduce nerve irritation 🔷 A step-by-step extension routine to reduce disc pressure 🔷 A simple nerve mobilization exercise to restore movement and blood flow If you’ve been jumping from clinic to clinic, video to video, or exercise to exercise without lasting relief, this episode will help you understand what your pain pattern actually means—and what to do about it. 📲 Work With Me ✅ Text “PAIN” to +1 (317) 751-9509 to get my FREE Sciatica Fix Demo. 👉 Apply for my 1:1 Online Low Back Program: www.therehabfix.com/low-back-program 📸 Follow @rehabfix on Instagram for hundreds of free low back and sciatica videos: www.instagram.com/rehabfix ⏱ Chapters 00:00 – Sciatica Pain Patterns Explained 00:36 – L4 vs L5 vs S1 Nerve Root Symptoms 01:22 – Why Leg Pain Comes From the Low Back 01:58 – Step 1: Unload the Spine (90-90 Position) 02:52 – Step 2: Extension Press-Ups 03:48 – Step 3: Sciatic Nerve Mobilization 04:44 – Why You Must Treat the Root Cause 05:28 – How to Get Your Free Sciatica Fix Demo 🔑 Keywords That May Have Brought You Here: sciatica nerve root, L4 L5 S1 sciatica, which nerve is causing sciatica, sciatica pain patterns, disc herniation leg pain, sciatic nerve pain relief, lower back nerve pain, sciatica exercises at home, 3 step sciatica routine, reduce disc pressure, pinched nerve in lower back, nerve root compression, sciatica treatment without surgery, sciatica relief exercises, herniated disc sciatica, centralization process, low back disc pain, sciatica physical therapy, sciatica routine at home, nerve flossing for sciatica, disc bulge exercises, sciatica nerve glide, lower back pain with leg pain, sciatica rehab exercises, RehabFix sciatica, Dr Grant Elliott sciatica. #️⃣ Hashtags #Sciatica #NervePain #DiscHerniation #LowBackPain #SciaticaRelief #BackPainRelief #RehabFix #PhysicalTherapy #SpineHealth #PainFreeLiving
