Sprainâcomplete or incomplete tear in supporting ligaments surrounding a joint caused by a twisting or wrenching motion. Strainâacute or chronic injury to a muscle or tendinous attachment caused by stress, overuse, or over stretching. Classified as mild, moderate, or severe (see Classifying sprains and strains)
