You should definitely go to the doctor for that. Sad you have to go through surgery at a young age, but if it fixes the issue maybe it's worth it.Sadly, I don't know what to do. My mom thinks it's a loose tendon in my knee but we don't know whats happening to my ankles.
Ranting a bit more here: I was bucked off a horse several years ago. Ever since my leg I have had so much pain in my leg, numbness (Like, I can't feel anything), and I have tons of tingling on my good days. Doctors think it's a pinched nerve and maybe doing surgery someday.
I think I'm done for now.
