About this condition
A herniated intervertebral disc occurs when some disc material moves beyond its usual boundary. It can irritate a nerve root, but similar findings are sometimes seen on MRI in people without significant symptoms.
What you should know
The size of a disc herniation is not a reliable measure of symptom severity on its own. Decisions depend on pain distribution, weakness, sensation, duration and the examination rather than the scan report alone.
Symptoms and reasons for assessment
Back or neck pain may spread into a leg or arm, sometimes with tingling, numbness or muscle weakness. Worsening weakness, changes in walking or altered sensation deserve attention even if pain has not increased.
Other possible explanations
Muscle strain, joint problems, other nerve conditions and non-spinal problems can cause overlapping symptoms. A protrusion or herniation on imaging is not automatically the cause of a person’s pain.
How the problem is assessed
The clinician relates symptoms to neurological examination, strength, reflexes and sensation. MRI is used when clinically indicated and likely to change management, not routinely for every backache. Referral to a neurosurgeon may be appropriate in selected cases.
Treatment and follow-up options
Without warning signs, conservative care often includes activity as tolerated, suitable exercise, adjusted loading and symptom relief when prescribed. Manual techniques, if considered at all, require an individual safety assessment and do not mechanically “put the disc back”. Not every herniation requires surgery.
When urgent care is needed
Increasing leg weakness, numbness in the saddle area, new loss of bladder or bowel control or inability to pass urine requires immediate emergency assessment. Severe pain after trauma or with fever also requires prompt evaluation. Call 103 for a serious emergency.

Frequently asked questions
Does a herniated disc always need surgery?
No. Many people are initially managed conservatively, provided there are no dangerous neurological signs.
Can treatment be chosen from MRI alone?
No. The scan must be interpreted alongside symptoms and examination.
What are emergency signs of nerve compression?
New bladder or bowel dysfunction, saddle numbness and progressive weakness need urgent assessment.
