How Can Torn Ankles Be Treated?

I tripped yesterday and hurt my left side. I already torn the ligaments in my ankle last year so the bone sticks out more on that foot meaning that I hurt it easily and a lot more ofter. My ankle is hurting me but my ribs are leaving me in the most pain. My false ribs on that side are hurting so much that I can barely move. My family say it's just bruised but there is no visable bruising and I've bruised bones before. This feels worse. I can't get to the walk-in centre for a few days but I can't stand the pain. What is this and how could I help it?
