How do i know what kind of an injury i have (ankle/foot)?

I rolled my left ankle today while having practice. The right side of my foot hurts quite a bt. sometimes while i put enough pressure on it or it is in the right position some of the ligaments hurt or my alkalies will hurt. And at random times (which is quite often) my whole foot tingles. At first my foot was swollen and the swelling has gone away. The pain isn't excruciating, but I know its there. Should i get it checked out or just keep icing it? thank you in advanced
