Is your kid's backpack too heavy?
from U.S. News & World Report
When Dr. Preeti Parikh was in school, her friends and parents were concerned by the heavy weight on her shoulders – literally, the weight of her backpack. "Oh my god, what do you have rocks in here?" her parents would ask her. She never paid much attention to the back pain she was experiencing, but now the New York-based pediatrician is on a mission to educate families about the dangers of improper backpack use, which can affect posture, cause back pain and muscle sprains, and also spur more serious health situations. If a child feels numbness or tingling, for instance, this could even mean a pinched nerve.
