Understanding the Condition
What Is a Slipped Disc?
A slipped disc, also called a herniated or prolapsed disc, is when the soft, gel-like centre of a spinal disc (the nucleus pulposus) pushes through a tear in its tougher outer ring (the annulus fibrosus). The displaced material can press on nearby spinal nerves, causing pain, numbness or weakness that spreads into the arm or leg depending on the level involved. It most often affects the lower back, particularly the L4–L5 and L5–S1 levels, though discs in the neck are also commonly involved, and it is one of the leading causes of sciatica and lower back disability in adults aged 25–55. At Bewell's Novena clinic, opening soon, a Gonstead chiropractor assesses your spine by hand, segment by segment: observing your posture, checking for temperature differences along the spine with an instrument, and feeling how each level sits and moves. Any adjustment is made by hand, and only where the findings support it. Severe or worsening leg weakness, numbness in the groin or saddle area, or any change in bladder or bowel control needs urgent assessment by a registered doctor.
