How To Treat Sore Feet?

hi, 3 nights ago,i i jumped of a stage with only sandals on on holiday, landed flat on my heels and could instantly not walk on my left heel. i can walk on the ball off my foot but its just too sensitive on my heel. its not easy to stretch the achilles and after elevating the foot for a while, when i again begin to walk, it's just as sore. i'm currently abroad and looking at all options before i pay for a consult with the doctors over here. thanks
