Disc Herniation
A disc herniation happens when part of an intervertebral disc bulges or pushes out and may irritate nearby nerves.
When to get help quickly: Urgent review is important if there is worsening weakness, trouble walking, loss of bladder or bowel control, or numbness around the groin or inner thighs.
Common symptoms
Common symptoms include neck or back pain, pain shooting into an arm or leg, tingling, numbness, and sometimes weakness in the affected limb.
When imaging helps
Imaging helps when symptoms are severe, lasting, associated with nerve signs, or not improving as expected, especially if doctors need to confirm which disc is pressing on a nerve.
What radiology does
MRI is usually the best imaging test to show the disc, the nerves, and whether the spinal canal is narrowed.
What usually happens next
Many cases improve with time, pain treatment, and physiotherapy, though some severe cases need injections or surgery.
