Understanding the condition
What it is and what happens next.
What causes it, how it is diagnosed, and the treatment routes available in the UK.
What it is and how it feels
The cord and the cauda equina share a narrow canal with discs, bones and ligaments, and anything that compresses them - a massive disc prolapse, cancer deposits in vertebrae, abscess or haematoma - produces a recognisable pattern: back pain with progressive leg weakness and sensory change, unsteadiness, and the ominous trio of saddle numbness, urinary retention or incontinence, and loss of bowel control.
Diagnosis and treatment routes
These symptoms mean emergency assessment now - call 999 or go straight to A&E - because urgent MRI followed by surgery, radiotherapy or steroids, according to cause, preserves whatever function remains at the time of treatment far better than it restores what has been lost. Hours genuinely matter, particularly for cauda equina syndrome and metastatic compression. These symptoms are a medical emergency: call 999 straight away rather than waiting for any referral, because treatment is time-critical and every minute matters.
