Back-to-school sales are underway, so in this a mini summer episode of Talking About Kids I decided to address the “back” in “back-to-school.” That is to say, I examine lower back pain in students, its prevalence, its causes, and how to prevent it. Links to some of the resources I cite are at talkingaboutkids.com. Full-length Talking About Kids episodes return in mid-August with an important examination of fentanyl.
