My 12-year-old daughter injured her neck in gymnastics, and there's a big competition coming up. Our doctor says it's okay for her to participate, but I'm worried. Should I let her compete?

Your doctor's advice was probably based on the details of your daughter's injury, along with his or her experience with similar injuries. But if you have doubts, get a second opinion. Be prepared for the fact that the second opinion may be different from the first. Predicting the risk of a future neck injury is not an exact science. Studies have shown that doctors' advice on these matters depends on their length of time in medical practice and their area of specialty. Along with the advice from your doctor, weigh the risks and benefits before deciding to have your daughter return to sports.
