A sprained ankle, also known as a twisted ankle, or rolled ankle is an injury where sprain occurs on one or more ligaments of the ankle. Knowing the symptoms that can be experienced with a sprain is important in determining that the injury is not really a break in the bone. When a sprain occurs, broken blood vessels will hemorrhage into the tissue that surrounds the joint, causing a visible bruise. White blood cells responsible for inflammation migrate to the area, and blood flow increases as well. Along with this inflammation, swelling and pain is experienced. The nerves in the area become more sensitive when the injury is suffered, so pain is felt as throbbing and will worsen if there is pressure placed on the area. Warmth and redness are also seen as blood flow is increased. Also there is a decreased ability to move the joint. Movements - especially turning, and rolling of the foot - are the primary cause of an ankle sprain. The risk of a sprain is greatest during activities that involve explosive side-to-side motion, such as squash, tennis, or basketball. Sprained ankles can also occur during normal daily activities such as stepping off a curb or slipping on ice.Returning to activity before the ligaments have fully healed may cause them to heal in a stretched position, resulting in less stability at the ankle joint. This can lead to a condition known as Chronic Ankle Instability (CAI), and an increased risk of ankle sprains.
