If an ankle sprain is left untreated, it may lead to a chronically unstable ankle joint and, from there, to degenerative and arthritic changes in the ankle, as well as chronic tendon inflammation. It may also feel as if the ankle is constantly trying to give out, which can, from there, cause a re-injury of the ankle.
