hi, i am a teen girl who plays three sports year round. i have experienced pain behind my kneecap, behind my knee, and on the bone the the outside side of my ankle when i run. i was previously diagnosed with a strained hamstring, but that only answered the pain in the back of my knee, not my kneecap or ankle. my running shoes didn’t provide much support, so i had previously had problems with my achilles’ tendon, which was solved with more arch support. i was wondering what is wrong with my knee and ankle though.
