If you've been told you have a herniated disc, surgery may be the first thing on your mind — but for the large majority of patients, it's not necessary. Understanding how herniated discs behave, and which warning signs genuinely point toward surgery, can save you a great deal of worry. Here's how Dr. Chavarria approaches this question with patients in Reno and the Tahoe area.
Most Herniated Discs Heal on Their Own
A herniated disc occurs when the soft inner material of a spinal disc pushes through its outer ring and irritates a nearby nerve — often causing the sharp, radiating leg pain known as sciatica. It feels alarming, but the body is remarkably good at resolving these on its own.
Studies consistently show that the majority of lumbar disc herniations improve significantly within 6 to 12 weeks of conservative treatment. The body gradually reabsorbs the herniated fragment and inflammation around the nerve settles down. This is why Dr. Chavarria's approach is conservative-first: surgery is rarely the starting point.
Conservative Treatments to Try First
Before considering surgery, most patients benefit from a structured non-surgical plan, which may include:
- Activity modification and a short period of relative rest
- Anti-inflammatory medications to calm nerve irritation
- Physical therapy focused on core strength and posture
- Epidural steroid injections for more stubborn pain
- Time — often the most underrated treatment of all
When Surgery Becomes the Right Choice
Surgery — typically a minimally invasive microdiscectomy — becomes worth considering when conservative care has been given a fair trial and leg pain remains severe and disabling, or when specific red flags appear.
- Leg pain that remains severe after 6–12 weeks of appropriate conservative treatment
- Progressive weakness in the leg or foot (such as a developing foot drop)
- Numbness that is worsening rather than improving
- Loss of bowel or bladder control — a rare emergency called cauda equina syndrome that requires immediate evaluation
The Bottom Line
A herniated disc on an MRI is not, by itself, a reason for surgery. The decision depends on your symptoms, how they're changing over time, and how much they affect your life — not just the image. When microdiscectomy is the right call, it is one of the most reliable operations in spine surgery, relieving leg pain in over 90% of properly selected patients.
If you're weighing your options, Dr. Chavarria will give you an honest assessment of whether surgery is likely to help — or whether time and conservative care are your best path forward.
