Herniated Disc
A herniated disc happens when the soft center of a spinal disc pushes through its tougher outer layer. If the displaced material presses on a nearby nerve, it can cause pain, numbness, or weakness, most often in the low back or neck.
Symptoms
- Pain that radiates into an arm (neck disc) or leg (low-back disc)
- Numbness or tingling along the affected nerve
- Muscle weakness in the affected limb
- Pain worsened by certain positions or movements
Causes
Discs lose water and flexibility with age, making them more prone to tearing with everyday strain, lifting, or twisting. Genetics and repetitive load also play a role.
How it's diagnosed
A physical exam maps which nerve is affected, and an MRI can confirm the herniation and rule out other causes when treatment decisions depend on it.
How we treat it
Most herniated discs improve without surgery. Physical therapy and medication come first; when a nerve stays inflamed, an epidural steroid injection can reduce swelling around the nerve and support recovery.
When to see a physician
Get prompt evaluation for worsening weakness, and urgent care for loss of bladder or bowel control.
Common questions
Will I need surgery for a herniated disc?
Most people do not. The majority improve with conservative care and image-guided injections; surgery is considered only when symptoms are severe or persistent.
Can a herniated disc heal on its own?
Often, yes, the body can reabsorb disc material over time, and symptoms frequently settle with appropriate care.
