Chronic pain has been recognized for centuries, but it was often misunderstood. In ancient cultures, persistent pain was attributed to spiritual or supernatural causes. Hippocrates wrote about chronic conditions as distinct from acute injury, but medical approaches were limited until modern science explored the nervous system. In the 20th century, researchers discovered that chronic pain can result from changes in nerve sensitivity, not just lingering injury. This understanding gave rise to multidisciplinary pain clinics, emphasizing physical therapy, counseling, and conservative care. Today, pain management includes chiropractic adjustments, exercise, stress reduction, and lifestyle coaching. The shift from “pain as a symptom” to “pain as its own condition” has transformed treatment.
