Rolling your ankle can be a mild issue that gives a bit of soreness or tenderness for a day or two. Sometimes it can be so serious that you can't put even the tiniest amount of weight on the ankle without it hurting. Among other things, wearing an ankle brace to prevent rolling helps greatly for those playing sports, going for walks or just walking about home.
