Your MRI says herniated disc. What now?
A herniated disc on an MRI report sounds alarming, but on its own it is not a verdict. Disc changes are very common in people with no pain at all, many herniations shrink over time, and what matters most is whether the finding actually matches your symptoms. The next step is not panic or an operation: it is a careful examination that connects the scan to what you feel.
Why “slipped disc” is the wrong picture
The phrase “slipped disc” suggests something has moved out of place and needs to be pushed back. Neither is true. Each disc is firmly attached to the vertebrae above and below it and cannot slide out.
What can happen is that the gel-like centre of the disc pushes outwards through a weakness or tear in its tough outer ring. That is a herniation. It can certainly hurt, but it is very different from the broken, unstable spine that “slipped” makes people imagine, and that fear itself can make recovery harder.
What the words on your MRI report mean
- Disc degeneration (or desiccation, or a dark disc): the disc has lost some height and water. It is a normal part of ageing, very common after 40, and often causes no pain.
- Disc bulge: the disc spreads a little beyond its usual edge all the way round, like a burger pressed between two hands. Very common and often harmless.
- Protrusion: inner material pushes into the outer ring but not through it.
- Extrusion: material has pushed all the way through the outer ring but is still connected to the disc.
- Sequestration: a fragment has broken off and lies free in the spinal canal.
- Nerve root contact or compression: the disc material is touching or pressing on a nerve root. This is the finding most likely to explain leg pain, numbness or weakness, but only if your symptoms match that nerve.
Why the scan does not tell the whole story
MRI is an excellent tool that shows discs, nerves and ligaments in detail without radiation. But what the scan shows and what hurts do not line up as neatly as most people assume.
When researchers scanned adults with no back pain at all, a large share of them had bulges, herniations or worn discs. None of these people had symptoms. So a disc change on your report may be real but have nothing to do with your pain.
MRI scans the structure of the spine. It cannot scan the pain.
The reverse is also true. Pain can come from structures that standard spinal MRI does not show well, such as the sacroiliac joint, the small facet joints or the muscles. A “normal” scan does not mean nothing is wrong. In the book, Dr Zano describes a patient whose MRI showed a small disc bulge, while the examination pointed clearly to the sacroiliac joint. The bulge was a coincidence.
Treating the scan instead of the person is one of the most common and costly mistakes in back pain care.
What usually happens to a herniated disc
Here the evidence is encouraging. Studies that scanned the same herniation at several points in time have found that most lumbar disc herniations get smaller on their own, and some disappear completely. Larger extrusions and fragments are often more likely to shrink, because the immune system recognises the material as out of place and slowly breaks it down. That does not make a large herniation harmless, and it still needs proper assessment, but a big number on the report is not a reason to lose hope.
The timeline is weeks to months, not days, and it is rarely a straight line. Usually the leg pain eases first, then numbness and tingling, and the back pain settles last.
What to do next: a practical plan
- Check for warning signs first. If any of the signs in the list below apply, see a doctor or go to the emergency department before anything else.
- Get an examination that matches the scan to your symptoms. Does your pain follow the nerve that the report mentions? Do nerve tests reproduce it? Is there weakness or changed reflexes? Or does the examination point somewhere else?
- Bring your images and the report, not only the written summary.
- Start conservative care. For most disc problems this is the first approach: manual therapy chosen for your case, targeted exercise, sensible changes to daily activity and, if needed, pain relief from your doctor.
- Give it enough time. Judge progress over weeks, not days. If your pain is severe and not improving after a proper course of care, or weakness is getting worse, a surgical opinion becomes reasonable. Read more in Do you need surgery for a herniated disc?
At Bodywerks, the first visit includes a full history, a nerve and movement examination and a look at your scans. If chiropractic care is not right for you, we will say so. For disc problems that need regular care, we offer a Sciatica and Disc programme: €720 for 12 weeks with as many visits as your plan requires. Whether it suits you is decided at the first visit.
When to see a doctor straight away
- New difficulty passing urine, or loss of bladder or bowel control.
- Numbness in the saddle area: groin, inner thighs, genitals or buttocks.
- Leg weakness that is getting worse over hours or days.
- Back pain with fever, unexplained weight loss, a history of cancer, severe pain at night, or after a significant fall or accident.
The first three can be signs of cauda equina syndrome and need the emergency department straight away. See also back pain red flags.
Frequently asked questions
Can a herniated disc heal on its own?
Often, yes. Repeat MRI studies show that many lumbar disc herniations shrink over weeks to months, and some disappear. Symptoms usually improve gradually, with leg pain easing before back pain.
Does a bulging disc on my MRI explain my back pain?
Not necessarily. Disc bulges are common in people without any pain. Whether yours is relevant depends on whether your symptoms and examination match it.
Is a large herniation worse than a small one?
Not automatically. What matters is where the herniation is and whether it is pressing on a nerve that matches your symptoms. Larger herniations are often more likely to shrink over time, but they still need a proper assessment.
Should I bring my MRI to a chiropractor?
Yes. Bring the images and the report. They help, but the examination decides how they are interpreted and what the treatment plan looks like.
If you have an MRI report and want to understand what it means for you, book online at our clinics in Limassol and Nicosia, or message us on WhatsApp and bring your scans to the visit. The first visit is €70 and includes treatment when appropriate. If treatment is not suitable or an X-ray is needed first, there is no charge. More about the 12-week Sciatica and Disc programme.
