The research could do some serious good for those suffering from chronic pain and other ailments. Right now, the research team has demonstrated only limited success. In its study, the patient's threshold for pain increased by 36 percent, but what's known as clinical pain--like the pain caused by a migraine, for instance--was not actually alleviated. So the procedure currently treats the symptom more than the actual ailment, and that's okay. By using natural painkillers to manage pain, patients could avoid the side effects of manufactured opiates which include--among other things--powerful addiction. The next phase of the research will explore whether this method can be finessed to actually reduce clinical pain as well as boost pain tolerance.
