EE went to a personal Dr. for carpal tunnel syndrome on 7/20 where the injury deemed was most likely work-related due to the repetitive motion of EE's wrist while fabricating. There were prior reporting's for personal concerns with EE's wrist before 7/20, but no injury or cause was determined until 7/20. EE at Duluth stated to use DOI as 7/20 and not any prior date.
