@anatomymuscl: 🚨 What if your leg isn't the real problem? That sharp, shooting pain traveling down your leg may actually start in your lower back, not in your calf or foot. Sciatica is often caused by irritation or compression of the sciatic nerve due to a herniated disc, poor posture, weak core muscles, or tight hip muscles like the piriformis. Understanding the root cause is the first step toward long-term relief—not just temporary pain relief. Learn how your spine, nerves, and muscles work together so you can make smarter decisions about your recovery. 💾 Save this video for future reference. 💬 Have you ever felt pain running from your lower back into your leg?
