Disc-Related Pain (Bulges and Herniations)
Your spinal discs act as shock absorbers with a gel-like center surrounded by tough outer rings. When stress causes the inner gel to push against or through those outer layers, you get a bulging or herniated disc.
| Feels like | Deep central ache + leg pain (often below the knee), may include numbness or tingling |
|---|---|
| Worse with | Sitting, bending forward, coughing, sneezing |
| Better with | Standing, walking, lying face-down |
| Key insight | If leg pain retreats toward your spine with certain movements (centralization), that's a positive prognostic sign (Long et al., 2004) |
