Most herniated, slipped and bulging discs get better without surgery. Guidelines put exercise, physiotherapy and time first, and research shows many disc herniations shrink on their own over months. Surgery is usually for emergencies, worsening weakness, or pain that has not improved after a proper course of non-surgical care. Between the two sit injections: steroid, PRP and, in early studies, stem cells.
Do you need disc surgery?
Ask yourself three questions:
- Is it an emergency? Numbness around the groin or buttocks, new problems controlling bladder or bowels, or weakness in both legs: go to an emergency department now. See when disc surgery is needed.
- Is weakness getting worse? A foot that slaps or drags, or a hand that keeps losing grip, needs an urgent specialist review.
- Has non-surgical care had a fair chance? For most people, that means 6 to 12 weeks of active treatment.
If the answers are no, no and no, you probably have time to try other options first. Read do I need disc surgery?

What the research says
- A Dutch trial in the New England Journal of Medicine (Peul, 2007) found early surgery for sciatica gave faster leg-pain relief, but at one year results were similar to prolonged non-surgical care.
- The US SPORT trials found both surgical and non-surgical patients improved substantially.
- A 2015 review found disc herniations often shrink by themselves over time.
- UK NICE guidelines advise against spinal fusion for low back pain outside research trials.

Told you need surgery?
Before agreeing to an operation, ask what happens if you wait, which non-surgical options you have not tried, and whether injections such as PRP or stem cells could fit your MRI. A free second look at your scan helps: send your MRI for a doctor review.
