A candy merchandiser who sustained a work-related injury to her right shoulder, suffered injuries to her neck and left shoulder as a consequence of overuse following the initial injury. The insurer denied the claim for injury to the left shoulder and neck as a consequence of overuse. Attorney McNamara successfully prosecuted the claim for consequential injuries to the left shoulder and neck. Because the initial right shoulder injury and its consequences have resulted in permanent loss of use to both arms, such that they may not be used for purposes of gainful employment, a claim for lifetime wage loss may be filed upon expiration of the 500 week maximum compensation period.
