When a 65-year-old woman in South Korea went to the hospital for routine tests, she expected doctors to tell her what she already knew—that her painful, swollen knees were caused by arthritis. Instead, her X-ray revealed something no one could have predicted: her joints were filled with hundreds of tiny gold needles. The shocking discovery left doctors stunned and raised questions about a little-known treatment practice that had gone far beyond what most people would consider safe.
The woman had been struggling with osteoarthritis, a common but painful condition where the cartilage in joints wears down, causing stiffness and inflammation. Traditional treatments such as pain medication and anti-inflammatory drugs hadn’t worked for her, and the side effects were becoming unbearable. Desperate for relief, she turned to acupuncture, a centuries-old practice widely used across Asia. Unlike standard acupuncture sessions, however, this treatment involved leaving thin gold needles in her body permanently, with the belief that they would provide continuous pain relief.
But what might sound harmless in theory quickly raised red flags in the medical community. Experts warn that leaving metal objects inside the body carries serious risks. The immune system can attack the foreign material, leading to chronic inflammation or tissue damage. Infections are also a major concern, and the presence of metal can make diagnostic scans harder to interpret, complicating future medical care.
Perhaps the greatest danger comes if a patient with these implants ever needs an MRI. Because MRI machines use powerful magnetic forces, metal objects can shift or move inside the body, potentially puncturing blood vessels or damaging tissue. While acupuncture remains a respected and widely practiced therapy for pain management, doctors stress that extreme variations—like permanent gold needle implants—should be approached with caution. This woman’s case, published in the New England Journal of Medicine, is a reminder that even traditional remedies can carry unexpected risks when taken to unconventional extremes.
