An ankle sprain is a common injury to the ankle. The most common way the ankle is injured is when the ankle is twisted inward (inversion injury). With this injury, ligaments that support the ankle can be torn which lead to swelling, inflammation, and bruising around the ankle. An ankle sprain injury may take a few weeks to many months to fully heal.
