Suggest Treatment For Leg Pain Caused After An Injury

I was walking running the down the stairs when I lost my footing. My left foot hit the step below me and it was a bad angle. I felt something pop. Not like a bone break, but more like if you were to pop yourself really hard with a rubber band, but on the inside. This was about 2 hours ago. I can bare some weight but not much. It is not terribly swollen nor barely any bruising. I am nurse, so I immediately iced it and elevated it. The pain anatomically fells like it is in the post. talofib lig, ant talofib lig, and the calcaneofib lig. At least where I thinlk they are. Again minimal swelling/bruising, hurts like hell to bear weight and walk but doable. Circumduction hurts pretty bad. Do i need to run out and get this looked at, or can I baby this myself? I am leaving to go on vacay for a week tomorrow!!!
