If you're under 16yr. Thanks for your interest in healthtap. Your question might not get answered if you are under age 16 years and writing your own questions. Have a trusted adult or parent submit your questions, using your account to ask about your concerns. There are many pediatricians on healthtap with a great deal of expertise, but they look for questions submitted by adults on behalf of teens or younger children.
