Answer:
swelling
Step-by-step explanation:
A sprain is an injury that affects the ligaments of a joint. The most common ones usually affect the knees and ankles and cause consequences that vary with the degree of injury. The causes of sprain are related to a sudden movement, usually torsion, that damages the ligaments of the joint. High-performing athletes, such as tennis players, soccer players, volleyball and basketball, for example, are more likely to suffer a ligament injury than a non-sports person.
When sprain occurs, in addition to pain, swelling may occur in the affected region.
