A herniated disc, also called a slipped or prolapsed disc, is when the soft centre of one of the cushions between the bones of the spine pushes out and can press on a nerve. It is a common cause of low back and leg pain, and most people feel better within a few weeks or months without surgery.
Overview
The discs between the vertebrae act as shock absorbers. Each has a tough outer ring and a soft, jelly-like centre, and a herniation happens when that centre pushes through the outer ring (AAOS OrthoInfo).
It is most often the result of age-related wear and tear, though a fall or other injury can also cause it. It most often affects the lower back (AAOS OrthoInfo), and it can also happen in the neck (MedlinePlus).
Not every slipped disc causes symptoms (NHS). When it does, the outlook is usually good: the AAOS says most people are free of symptoms by 3 to 4 months, and in many cases the herniated material is gradually absorbed by the body.
Common symptoms
- Lower back pain, often the first symptom
- Sciatica: sharp, often shooting pain from the buttock down the back of one leg
- Numbness or tingling in the leg or foot, or in the shoulder, arm or hand if the disc is in the neck
- Weakness in the leg or foot
- Neck pain, or difficulty bending or straightening your back
Common causes
- Age-related wear and tear: discs lose water and flexibility over time, which makes them more likely to tear or bulge
- A fall or other injury
- Lifting with your back rather than your legs, especially while twisting
- Jobs with repetitive lifting, bending or twisting, and long periods of driving or sitting
- Being overweight, inactive or a smoker
- The AAOS notes men aged 20 to 50 are the most likely to be affected
Warning signs to act on
The sources list these as warning signs. Each one says what the source advises: some are emergencies (in the US, call 911 or go to the emergency room), others mean contacting a clinician promptly.
- Loss of bladder or bowel control: the AAOS says this is extremely rare and may be a sign of cauda equina syndrome, a medical emergency
- Numbness around your bottom or genitals, losing feeling in one or both legs, or back pain after a serious accident: the NHS treats these as emergencies
What usually helps
A short rest, then gentle activity
The AAOS says one to two days of rest can ease pain but advises against staying off your feet for longer. The NHS says you will recover more quickly if you gradually start gentle exercise such as walking or swimming.
Anti-inflammatory pain relief
The NHS and AAOS list anti-inflammatory painkillers such as ibuprofen. They are not suitable for everyone, so the NHS suggests speaking to a pharmacist if you're not sure you can take them.
Physical therapy
MedlinePlus describes physical therapy as important for nearly everyone with disc disease: therapists teach safe ways to lift, move and strengthen the muscles that support the spine.
Injections and surgery
If pain persists, a steroid injection may give short-term relief. The AAOS notes that only a small percentage of people need surgery, usually after nonsurgical care hasn't relieved symptoms, or for muscle weakness, difficulty walking, or loss of bladder or bowel control.

Will Your Disc Heal. It Depends. Bulge? Herniation? Protrusion? Extrusion? Sequestration?

Frequently asked
- Can a herniated disc heal on its own?
- Often, yes. The AAOS says most people improve over days to weeks and are usually free of symptoms by 3 to 4 months, and the herniated material is often absorbed by the body over time.
- Is a slipped disc the same as a herniated disc?
- Yes. Slipped, prolapsed, herniated and ruptured disc are different names for the same problem (NHS; AAOS OrthoInfo).
- When is surgery needed for a herniated disc?
- The AAOS says only a small percentage of people need it, and that surgery is typically recommended only after nonsurgical treatment hasn't relieved symptoms, or for muscle weakness, difficulty walking, or loss of bladder or bowel control. The NHS lists symptoms that haven't improved with other treatments, or worsening muscle weakness or numbness, as reasons to discuss surgery.
- Can a herniated disc come back?
- It can. The AAOS puts the chance of the disc herniating again at up to 20 to 25% over a lifetime, with or without surgery.
- Who treats a herniated disc?
- MedlinePlus describes physical therapy as important for nearly everyone with disc disease. In its spinal stenosis guide, the AAOS advises care with chiropractic manipulation if you have a herniated disc, as it can worsen symptoms or cause other injuries. You can find physical therapists near you in the SpinalCare directory.
