Overview
About Slip Disc Evaluation
A herniated, or "slipped," disc occurs when the soft inner material of a spinal disc bulges or ruptures through its tougher outer layer, sometimes pressing on a nearby nerve. It can occur in the neck (cervical) or lower back (lumbar) region and may cause local pain alone, or radiating pain, numbness, and weakness if a nerve is compressed. Evaluation combines a detailed history and neurological examination with MRI to confirm the disc level, the size of the herniation, and whether a nerve is affected. Most patients improve substantially with structured conservative treatment, with surgery reserved for those with significant or progressive nerve symptoms.
Key Benefits
MRI confirms the exact disc level and severity of herniation
Neurological examination identifies whether and how much a nerve is affected
Clear guidance on whether conservative care or surgery is appropriate
Conservative-first approach avoids unnecessary surgery in most cases
Early evaluation prevents progression to more severe nerve damage
Frequently Asked Questions
What is the difference between a bulging disc and a herniated disc?
A bulging disc has the outer layer intact but extending slightly outward, generally less likely to compress a nerve. A herniated (slipped) disc has a tear in the outer layer with inner material protruding, more likely to cause nerve compression and radiating symptoms.
How is a slip disc diagnosed?
Diagnosis begins with a focused history and neurological examination assessing reflexes, strength, and sensation, followed by an MRI of the spine to directly visualise the disc, confirm the level, and assess any nerve involvement.
Can a slipped disc heal on its own?
Yes — over time, the body often reabsorbs herniated disc material, and inflammation around the nerve settles. Many patients see significant improvement in symptoms within 6–12 weeks with conservative treatment alone.
What treatment is given for a slip disc?
Initial treatment includes anti-inflammatory medication, activity modification, and physiotherapy. If pain persists, an epidural steroid injection may be used. Surgery is reserved for cases with significant or worsening nerve symptoms.
When is surgery required for a slipped disc?
Surgery (typically microdiscectomy) is considered when there is significant leg or arm weakness, symptoms that fail to improve after 6–8 weeks of conservative treatment, or urgently if there are red-flag signs like loss of bladder or bowel control.
