ABOUT THIS EPISODE
Your MRI shows a disc problem. But is it a herniation or a bulge — and does the difference actually change anything?
The answer is yes. And in this episode, Dr. Chris Cameron explains exactly what that difference is, why it matters clinically, and what it means for how your pain is treated.
This is one of the most commonly confused topics in spinal health — and one of the most important to get right before you make any decisions about your care.
