Is Surgery Necessary for a Herniated Disc?

"My MRI shows a hernia — am I going to need surgery?" The answer to this question is more reassuring than most people expect: the large majority of herniated discs improve without surgery. A hernia showing up on an MRI doesn't, on its own, mean surgery is needed.

It's the clinical picture that decides, not the image

The most common mistake is trying to make the surgery decision based only on the size of the hernia on the MRI. In fact, a significant proportion of healthy people with no complaints at all also show a hernia on MRI. The decision is made based on the severity of the pain, nerve findings and how the picture progresses over time — not just by looking at the image.

Non-surgical treatment is usually the first choice

For herniated discs without a red flag, the path guidelines recommend is non-surgical treatment first, because these conditions usually improve noticeably within a few weeks to a few months. The components of the non-surgical process:

• Bringing pain in the acute phase down to a manageable level (physician-managed medication and relative activity — not bed rest)
• Neural mobilisation aimed at letting the nerve glide freely
• Gradually training the deep trunk muscles that support the back
• Hip and hamstring flexibility
• Daily-life adjustments and a home programme that teach how to move while protecting the back

"Does a hernia get reabsorbed?"

Surprising but true: the herniated disc fragment can shrink over time, and can even be reabsorbed by the body. This is why non-surgical recovery is seen so often. The goal isn't to "push the hernia back into place" — it's to manage the pain while giving the body time to heal and to make the back able to carry load again.

When is surgery genuinely needed?

Surgery is needed for a minority of specific conditions, and this decision is made by the surgeon. The main situations:

Urgent (red flags). Loss of bladder/bowel control, numbness in the saddle area (inner thigh – anus), foot drop, or rapidly progressing muscle weakness. These require surgical assessment without delay.

Not urgent but persistent. Leg pain that seriously restricts life not resolving despite an adequate and regular non-surgical treatment (usually 6-12 weeks).

Outside these two situations, the severity of the pain alone isn't a reason for surgery.

Who makes the surgery decision?

The healthiest approach is not leaving the decision to one person: surgical assessment runs through neurosurgery / orthopaedics, while the non-surgical process runs through physical medicine and physiotherapy. A good surgeon usually also recommends non-surgical methods first; surgery is the option at the end of the line, not the first one.

I had surgery — does physiotherapy end?

Quite the opposite. Even after surgery, the muscles that support the back need to be re-strengthened, correct movement needs to be learned, and a programme that prevents the hernia from recurring needs to be built. Surgery resolves one part; the back's long-term health is still protected through exercise.

Frequently asked questions

How long does the non-surgical process take?

In most cases, noticeable improvement is seen within a few weeks to a few months; the duration depends on the size of the hernia and how consistently the programme is followed.

If I have surgery, will I fully recover?

Surgery relieves the pressure on the nerve, but the back's long-term health is still protected through exercise and correct movement; surgery alone isn't a guarantee.
