Today when I ran up a ramp, my ankle popped and it immediately swell. I couldn t really bare the pain, but managed to get up and limp. It was fine for a while, but when I walked up the stairs, it popped twice and I was in excruciating pain. The swelling increased. Now, it feels like there is an air bubble in my ankle that will pop at any moment. It is hard for me to walk, especially on stairs. Also, I can barely move my ankle, and it is still swollen. Is my ankle dislocated, fractured, or sprained?
