Is it possible to sprain your ankle and not swell?

Yes, it is possible to sprain your ankle and not experience swelling. Sprains are caused by the tearing of ligaments, which are the bands of tissue that connect bones together. Swelling is a common symptom of a sprained ankle, but it is not always present. This is because swelling is caused by inflammation, which is the body's natural response to injury. In some cases, the inflammation may be mild and not cause any noticeable swelling.
