Bulging Disc
The disc flattens and spreads outward past its normal edge, a bit like a tyre that is low on air, but the tough outer wall stays intact and nothing leaks out. The bulge usually involves a wide section of the disc and comes on gradually with age and wear.
- Outer wall intact, nothing escapes
- Often affects a broad part of the disc
- Builds slowly, and may cause no symptoms at all
- Symptoms tend to be a dull ache or stiffness
