What Really Causes Sciatica? It’s Not Always a Slipped Disc | Deep Dive Epi 2

Is that shooting pain down your leg really caused by a slipped disc, or is something outside your spine pulling the strings? Discover the true causes of sciatica, why your MRI scan might be misleading you, and the critical red flags that demand an immediate trip to the ER. 2. Video Description When severe, electric-shock pain shoots from your lower back or buttock down into your calf and toes, most people assume they have a massive, dangerous slipped disc. But what if a visible disc bulge on an MRI has absolutely nothing to do with the pain you feel? In Episode 2 of our 6-part masterclass series on 'Podcast with Prakash' (Deep Dive: What Really Causes Sciatica?), we break down: • Sciatica Is Not a Diagnosis: Why radiating nerve pain is just a symptom alarm—like a fever—rather than the root illness. • True Spinal Mechanisms: Herniated discs (mechanical squish vs. chemical burn), lumbar spinal stenosis, and the fascinating physics behind the "shopping cart sign." • Vertebral Kinks & Cysts: Degenerative vs. isthmic spondylolisthesis and facet joint synovial cysts. • The Great Mimickers: Piriformis syndrome (deep gluteal entrapment), hip osteoarthritis referred pain, SI joint dysfunction, diabetic peripheral neuropathy, and vascular claudication. • Shingles Surprise: How the varicella zoster virus mimics a pinched nerve days before a rash appears. • The MRI Dilemma: Why 30–40% of healthy, pain-free people walk around with disc herniations ("wrinkles of the spine"), and why clinicians treat the patient—never the scan. • Critical Red Flags: Cauda Equina Syndrome (saddle anesthesia, bowel/bladder incontinence) and foot drop—when surgery within 24 hours is non-negotiable. • The 4 Pillars of Diagnosis: How history, clinical neural tension testing (Straight Leg Raise), targeted imaging, and the healing power of time prevent unnecessary surgery. Whether you are deciding on physical therapy, spinal injections, or surgery, this deep dive provides the exact clinical clarity you need to avoid rushed, incorrect procedures.
