Dorsal Root Ganglion Stimulation: What Patients Should Know When Pain Stays in One Precise Spot

DRG stimulation may ease focal nerve pain such as CRPS by targeting the dorsal root ganglion. Learn how it differs from a spinal cord stimulator and peripheral nerve stimulation, and how the trial works.

• Why pain patterns and exam findings still matter when sciatica is suspected
• Why a herniated disc on cervical MRI does not automatically explain arm pain
• What Patients With Back or Neck Pain Wish Someone Had Explained About MRI Results — why an MRI can be useful but may not fully explain pain by itself.
