Sprained/fractured ankle about a year ago and still experiencing pain. What do i do?

I sprained/fractured my ankle doing a back tuck over a year ago and I am still having trouble with it. I never went to a doctor so idk what i really did but all ik is that it hurt like a *****! I was still able to walk and it didnt bruise too bad but it was very very swollen and hurt to move. I cannot go onto my tippy tippy toes on the hurt ankle and when i sit in a weird was or have it bend for too long while laying down it starts to hurt very bad. I can walk and run and jump fine but its really a bother and idk what to do
