Herniated Disc
One of the most common causes of back and leg pain
ICD-10: M51.1 · lumbar condition
A herniated disc — also called a slipped or ruptured disc — occurs when the soft inner gel of an intervertebral disc pushes through a crack in its tougher outer layer. This can irritate nearby nerves, causing pain, numbness, or weakness that may radiate into an arm or leg. Herniated discs most often occur in the lower back (lumbar spine) or neck (cervical spine).
5–20%
Approximately 5–20% of adults experience a herniated disc at some point in their lifetime, with peak incidence between ages 30–50.
American Academy of Orthopaedic Surgeons90%
About 90% of herniated disc cases resolve without surgery within 6 weeks of conservative treatment including physical therapy and anti-inflammatory medications.
North American Spine Society90%
The lumbar spine accounts for approximately 90% of all disc herniations, with the L4–L5 and L5–S1 levels most commonly affected.
American Academy of Orthopaedic SurgeonsSymptoms
- Sharp, burning pain in the lower back, buttock, leg, or foot (sciatica)
- Arm or shoulder pain that worsens with certain movements (cervical herniation)
- Numbness or tingling in the leg, foot, arm, or hand
- Muscle weakness in the affected limb
- Pain that worsens with prolonged sitting, coughing, or sneezing
- In severe cases: loss of bladder or bowel control (seek emergency care)
Causes & Risk Factors
- Natural disc degeneration with age (most common)
- Sudden strain from lifting heavy objects with poor technique
- Repetitive twisting or bending motions
- Trauma such as a fall or car accident
- Excess body weight placing added stress on discs
- Genetic predisposition to disc problems
- Sedentary lifestyle and prolonged sitting
Treatment Options
Conservative
- Physical therapy and targeted exercises to strengthen core muscles
- Anti-inflammatory medications (NSAIDs) or oral steroids for pain flares
- Epidural steroid injections to reduce inflammation around the nerve
- Activity modification and ergonomic adjustments
- Hot/cold therapy and gentle stretching
- Chiropractic care (selected cases)
Surgical
- Microdiscectomy — minimally invasive removal of the herniated fragment
- Lumbar laminectomy to relieve pressure on spinal nerves
- Anterior cervical discectomy and fusion (ACDF) for cervical herniations
- Total disc replacement (arthroplasty) as an alternative to fusion in some patients
When to see a spine specialist
See a spine specialist if your pain does not improve within 4–6 weeks of conservative care, if you develop weakness in a limb, or if you experience any loss of bladder or bowel control (emergency).

Search spine specialists →Frequently Asked Questions
Can a herniated disc heal on its own?
Yes — in many cases. Studies show that the herniated material can shrink over time as the body reabsorbs it. Up to 90% of patients improve within six weeks with conservative treatment alone. Surgery is reserved for cases where conservative care fails or neurological symptoms progress.
What is the difference between a herniated disc and a bulging disc?
A bulging disc is when the entire disc extends slightly beyond its normal boundary, like a slightly flat tire. A herniated disc is a more focal problem — the inner gel has pushed through a tear in the outer wall. Herniations are more likely to directly irritate spinal nerves and cause radiating symptoms.
How long does herniated disc recovery take?
Most patients with a herniated disc improve significantly within 4–6 weeks of conservative care. Full recovery varies: some patients are back to normal activities in 6–8 weeks, while others with more severe herniations may take 3–6 months. After microdiscectomy surgery, most patients return to light activities within 2–4 weeks.
Is surgery always needed for a herniated disc?
No. Surgery is generally not the first option. Most spine specialists recommend at least 6–12 weeks of conservative treatment (physical therapy, medications, injections) before considering surgery. Exceptions include rapidly progressing weakness, loss of bladder or bowel control, or severe, unrelenting pain.
