Hi I'm An 8th Grader And I Do Track And

Hi I'm an 8th grader and I do track and when I first had my meet where I compete against people, after that my ankles have been hurting really bad to the point where I want to cry, when I run, it was my left ankle, when I went to my second meet I thought I was going to be okay because my mom bought me a brace and it felt a little better, I wore my brace when I ran then after it hurt really bad again, not just with my left ankle with both of my ankles now. Now every time I just speed walk both starts to hurt:( Do you think u can help me what to do? Do I need to go to the doctors and get a brace that will help my ankles?
