I sprained my ankle about 4 years ago and continued walking around on it. I had it x-rayed a month after I sprained it and nothing was wrong but I still had pain. Now my ankle is hurting a lot and I don't know why it is. It makes a cracking noise when I move it so I wrap it up every night. Does anyone know what could be the problem? I want to go to the doctor but I just want to make sure this pain isn't normal. Please help!!
