Step-by-step explanation:
Sprain is an injury to a joint or its ligaments. This occurs for a variety of reasons, such as crashes and accidents, but is much more common in people who play sports. There are three degrees of severity for sprains, with grade 1 sprain being the mildest, which only causes some stretch in the fibrous tissue, and grade 3 sprain, the most severe, which causes total rupture of the fibrous tissue.
