Interventional pain medicine is a medical subspecialty that uses minimally invasive procedures, like nerve blocks, injections, and neuromodulation (spinal cord stimulators), to diagnose and treat chronic, persistent, or intractable pain. Physicians in this field use imaging guidance (like X-ray or ultrasound) to deliver treatments precisely to targeted areas, aiming to provide long-term relief and improve a patient's quality of life beyond what medications alone can achieve.
