Any doctors or nurses PLEASE help me!!!!!?

Ok I'm 13 and a girl and play soccer and basketball. My ankles and knees have always hurt me, but recently my Achilles on my left ankle has been hurting after practice alot and my right ankle pops alot and hurts when it does. I was going to ask my mom to take me to see a sports medicine doctor about it but wanted a second opinion first. PLEASE ANSWER!!!!!!!! Oh and if you know any good sports medicine doctors in Chattanooga could you tell me that to please. Thanks.
