Needle to the spine: can a direct shot ease your aching back?

This study tested whether injecting a steroid medication directly into a painful spinal disc could reduce chronic lower back pain. It involved 137 adults in France whose pain hadn't improved with standard treatments and who had signs of disc inflammation on an MRI scan. Participants were randomly assigned to receive either the steroid injection or a placebo procedure during a diagnostic test to see which provided better pain relief after one month and one year.
