Herniated Disc: Does Everyone Need Surgery?

No. Most people with a herniated disc in the lower back get better without surgery, usually over weeks to a few months. Surgery is the right choice for a smaller group, such as people with serious nerve signs or pain that does not settle with good nonsurgical care. That decision belongs to you and your spine specialist.

What a herniated disc is

Spinal discs are cushions between the vertebrae, with a tough outer ring and a softer center. A herniation happens when some of the inner material pushes through the ring. It can irritate a nearby nerve root and cause pain, numbness or tingling down the leg. That leg pain is often called sciatica, which the sciatica page covers.

Many discs shrink on their own

Herniated disc tissue can shrink, and sometimes disappear, without surgery. A 2015 review of studies on people treated without surgery found regression in 96 percent of sequestrated discs, 70 percent of extrusions, 41 percent of protrusions and 13 percent of bulges.

The types that sound worst, extrusions and sequestrations, were the most likely to shrink.

The American Academy of Orthopaedic Surgeons adds that most people feel better within a few weeks or months without surgery, and that most are free of symptoms by 3 to 4 months.

When surgery is the right call

The same academy notes that spine surgery is typically recommended only after a period of nonsurgical treatment has not relieved painful symptoms, or for people with muscle weakness, difficulty walking or loss of bladder or bowel control. Loss of bladder or bowel control is rare, but it can be a sign of cauda equina syndrome, a medical emergency.

For many others, surgery is a question of speed. In a Dutch trial published in 2007, people with sciatica from a disc had either early surgery or prolonged nonsurgical care, with surgery later if needed. Early surgery eased leg pain and brought a sense of recovery faster. At one year, though, outcomes were similar, and the chance of feeling recovered was 95 percent in both groups. In the nonsurgical group, 39 percent ended up having surgery, after an average of about 19 weeks.

So surgery can make sense when pain is severe or not improving. Your spine specialist helps you weigh it.

The MRI is only part of the picture

Disc findings are common in people with no pain at all. A 2015 review found disc protrusions on the scans of 29 percent of pain-free 20-year-olds, rising to 43 percent by age 80. Disc bulges rose from 30 percent to 84 percent. So a disc on your report may or may not be the main source of your pain.

What often keeps pain going is the response around the disc: protective spasm in the deep spinal muscles, trigger points in the buttock that mimic nerve pain, a nerve that stays sensitive as the disc heals, and a fear of movement that keeps muscles guarding.

If your legs tire or ache after a short walk and ease when you sit, the narrowing of spinal stenosis may be part of it, which the spinal stenosis page explains.

Where my care fits

My care does not fix the disc, and it does not replace your spine specialist. The first visit runs 60 to 75 minutes and includes checks of strength, reflexes and sensation to monitor nerve involvement. Dry needling releases protective spasm and trigger points around the injured level, working with nearby muscles rather than the disc itself. Alongside dry needling, I use neuro-functional acupuncture, built on neuroscience and evidence-based practice. Unlike regular electroacupuncture, the needles and gentle electrical stimulation are mapped to the specific nerves involved, such as the affected nerve pathway. It works in three ways. It neurorehabilitates, helping irritated tissues and nerve receptors recover. It neuromodulates, shifting the body's own pain-relieving chemistry. It neuroregulates, calming the nerve signals and circuits that keep radiating pain going. Results vary from person to person.
