A study in the Annals of Internal Medicine out April 17 provides evidence steroid injections for back pain are no more effective than a placebo. Because the long-term benefits of surgery remain unproven and pain medicines often have serious side effects, doctors have increasingly turned to steroid injections to treat lumbosacral radiculopathy, a common cause of back pain. The researchers conclude that steroids may provide some short-term analgesic effect, but that the improvement in all of the patients was mainly due to normal healing. The best thing for back pain, according to the study’s author? Exercise. See a quick summary of this research from the New York Times’ website.
