Tear: Discontinuity of muscle fibers typically at myofascial or myotendinous junction
Contusion: Direct blunt compressive trauma to muscle without definable tear
Hernia: Focal protrusion of part of muscle through epimysium
DOMS: Overuse causing muscle edema without definable tear
Pain peaking 1-3 days after overuse
