Ankle sprains often while participating in sports, walking on uneven surfaces, or just awkwardly planting the foot.
A sprain is an acute injury that can happen in the blink of an eye and typically occurs when the foot is twisted or turned out of its normal range of motion.
The most frequent type of sprain is called an inversion sprain, which is when the outer ligaments stretch or tear when the foot is rolled outward, with the sole facing in. Less common is a medial sprain, which is when the foot rolls inward and overstretches the inside ankle ligaments.
