Hi, My name is Kristen and I m 15. Today at school, I fell down some stairs, and immediately heard & felt my left ankle pop. It is really hurting now, like a throbbing/burning sensation, but there is little or no swelling . If i rub my finger against or under the side of that round bone on the outside of my ankle, it really hurts. My ankle is also tingling . What s wrong with my ankle?
