hairline or stress fracture ? what do you think. . . .?!

Alright, over christmas break i hurt my ankle at gymnastics. It was swollen and bruised, I couldnt walk for like 2 weeks, and now i have to wear a brace, it still hurts a lot to walk and stuff. I do tumble and stuff but it hurts a lot. And every morning when i wake up i cant walk on it, it hurts too much. And its only alittle bit bruised and swollen right now but not that bad, but it hurts sooooo bad !

Im going to the doctor tuesday, but im thinking maybe i have a hairline fracture or stress fracture, idkk though. What do you think ? PLEASE HELPP ! (:

Ps- the doctor im going to is for feet and ankles
