Sciatica Isn’t a Diagnosis: Why Treating Your Leg Keeps You Stuck
Sciatica isn't a diagnosis — it's a symptom description, and chasing the pain in your leg instead of the injury in your lower back is what keeps it coming back.
If you've been told you have sciatica, a trapped nerve or a pinched nerve, this session explains why that description is incomplete. The pain running down your buttock, thigh, calf or foot is generated by an injury higher up — usually a herniated disc, a disc bulge or spondylolisthesis irritating the nerve roots where they leave the spine — so stretching, massaging or icing the leg itself never touches the actual problem.

We explain why thinking in terms of "sciatic-type pain" rather than one strict diagnosis helps you trace symptoms back to their real source, why piriformis syndrome is usually muscle guarding rather than the cause, and why relief from an injection, a nerve block or nerve flossing is never the same as healing. We cover why going by how you feel day to day keeps people stuck in the same loop, why sitting can put more strain through an injured lower back than a careful, controlled squat, and why exercises like elephant walks, nerve glides and generic mobility routines are not rehabilitation. The common thread throughout: build the capacity of the injured lower back itself, rather than chasing the symptoms it's sending down your leg.
🔑 Key Topics Covered
🦵 Sciatica is a symptom, not a diagnosis: pain in the buttock, thigh, calf or foot is generated by an injury in the lumbar spine — a disc bulge, herniation or spondylolisthesis irritating the nerve roots where they exit — so treating the leg itself never resolves it.
🎯 Why piriformis usually isn't the real problem: a tight piriformis is most often muscle guarding reacting to the underlying lower back injury, the same way a sprained ankle can leave the opposite hip tight. Treat the injury and the muscle symptoms settle on their own.
🧵 Why nerve flossing doesn't work: nerves aren't designed to stretch, and the relief people feel from flossing, nerve glides and elephant walks comes from briefly opening up the same bony space a knee hug or child's pose opens, not from fixing anything, while keeping the injury flexed and irritated.
📉 Stop going by how you feel: flare-ups happen to everyone recovering from a back injury, and judging progress day to day instead of tracking your rehabilitation keeps you stuck in the same cycle.
💪 What sciatica recovery actually takes: building load-bearing capacity through the Core 6 — dead bug, marching bridge, squat, hip hinge, step up and single-leg hip hinge — so the spine itself gets stronger, rather than chasing temporary relief.
