Herniated and bulging discs

Overview

Understanding herniated and bulging discs

Discs sit between the bones of the spine and help absorb load. A bulge describes a broader extension of the disc contour, while a herniation describes a more focal displacement of disc material. The words are sometimes used loosely, so the imaging report and symptoms should be considered together.

Many disc findings are seen on scans in people without pain. Treatment should be based on the clinical pattern and function, not the scan wording alone.

Useful context

What people may notice

• Neck or low-back pain that changes with movement or position
• Pain traveling into an arm, buttock, or leg
• Numbness or tingling in a hand or foot
• Weakness when a nearby nerve root is significantly affected

At the clinic

How evaluation works

1. 01

   Compare the symptom distribution with a focused spine and neurologic examination.

2. 02

   Review when symptoms began and whether trauma, lifting, or another event was involved.

3. 03

   Interpret MRI or other imaging alongside the examination rather than in isolation.

4. 04

   Discuss activity, rehabilitation, medication, injection, and surgical referral options according to the findings and severity.
