Prescription painkillers might actually do more harm than good, according to a recent study.
Researchers at the University of Colorado Boulder tested opioids, like morphine, on rats and found a few days' worth of doses caused months of chronic pain.
The painkillers were found to spur a "cascade" of reactions that led to more pain signals being fired from nerve cells in the spinal cord and brain.
