Editor’s Introduction—Rethinking Pain: What We Are Treating, What We Are Missing, and Why It Matters

Pain is among the oldest challenges in medicine, yet we still often get it wrong.Not because we do not care, but because we have fractured its meaning.Across disciplines, pain is treated as a symptom, sign, disease, or dysfunction.For patients, however, it is something more: an existential crisis, a threat to identity, a loss of self.In this gap between the lived experience of pain and the siloed responses of our health systems, something essential is being missed.As guest editor for this special pain issue of the International Journal of Spine Surgery (IJSS), I invite readers to step back and ask: What, exactly, are we treating when we say we are treating "pain"?For whom, and toward what end?Spine surgeons, by training, address mechanical lesions.They decompress, stabilize, and fuse while attempting to preserve motion.Pain interventionalists apply ablative or neuromodulatory techniques to interrupt nociceptive signaling.Psychiatrists often encounter pain as a comorbidity, intertwined with depression or trauma.Patients, for their part, present with something messier-an aching, immobile body layered with loss, fear, dependence, and often despair.Each specialty touches truth-but none alone holds the whole.Our treatment paradigms have become increasingly precise while our diagnostic categories remain coarse.In our well-intentioned focus on the visible-stenosis, degeneration, nerve root compression-we risk neglecting the invisible: reward dysfunction, emotional collapse, and spiritual crisis (Box 1).Recent advances in neurogenetics have deepened this insight.Chronic pain, substance use, and even certain behavioral syndromes may share a common thread: disrupted dopamine tone.What Blum et al describe as Reward Deficiency Syndrome 2,3 represents a shift in how we might understand not just addiction, but pain itself.That is, for some patients, persistent pain may not stem from persistent injury but from a brain incapable of registering reward, safety, or relief.From this perspective, opioids may offer not just analgesia but temporary emotional homeostasis-albeit
