A 25-year-old female presents with swelling, pain, and inability to bear weight on her left ankle following a fall during a basketball game where she landed awkwardly on her foot. The pain is on the outer side of her ankle. What is the likely diagnosis and next steps?
This patient's history and symptoms are indicative of a lateral ankle sprain, one of the most common sports-related injuries. It occurs when the foot is inverted, causing damage to the lateral ligaments. The next step is a physical examination, including special ligamentous tests to confirm the diagnosis. An X-ray should also be done to rule out any associated fractures. Initial management would include rest, ice, compression, and elevation (RICE) protocol and analgesia.
