What a bulging disc actually is
A spinal disc has a tough fibrous outer wall and a softer centre. A bulge is a broad, generalised extension of that outer wall past its normal margin: the disc spreading slightly, rather than something breaking through it. That is different from a herniation, which is focal, and very different from a sequestration, where fragment material has separated.
Bulges are extremely common in people with no pain
This is the single most useful thing to know. Disc bulges show up routinely on scans of people who have never had back pain in their lives, and they become more common with each decade. Finding one on your scan does not establish that it is causing your symptoms. Matching the imaging to the clinical picture is what does.
So what can actually be done?
Three things, none of which involve repositioning anything:
- Reduce the irritation. Much of the pain in disc presentations comes from inflammation around the nerve root rather than mechanical pressure alone. That settles, and it can be helped to settle.
- Restore movement to what has stopped moving. Segments above and below an irritable level commonly stiffen up protectively, which increases the load on the level that is already unhappy.
- Change what the disc is being asked to carry. This is the part that lasts. If your hips do not extend and your trunk does not share load, one lumbar segment keeps taking more than its share, and it will keep doing that after the current episode settles.
What we would use
- Adjustment, with technique chosen for the presentation: an irritable disc is not treated like a stiff facet joint, and low-force options are available
- Cold laser therapy during the irritable phase
- Spinal decompression on the Chattanooga Triton DTS where the presentation suits it, to offload the segment while things settle
- Rehabilitation to rebuild capacity: the part that determines whether you are still well in a year
How we assess it
A first visit runs about 30 minutes: history, neurological testing, nerve tension testing, and a segmental examination of movement and load. If you have a scan report, bring it — but expect us to examine you rather than treat the report.
When the answer is someone else
We cannot help a disc that has sequestered. Progressive neurological deficit, or symptoms suggesting cauda equina syndrome — loss of bladder or bowel control, numbness around the groin or inner thighs — need medical or surgical review, urgently. You will be told that on the first visit, not the sixth.
