Hello, Had carpal tunnel surgery in March of 2009. Recieved WC for time off. Returned to work. In Jan of 2010 returned to Dr with more wrist pain. Now 3 torn ligaments and need ulnar shortening. WC will cover again but telling me at same rate of pay as original injury. This is a different injury,not carpal tunnel. shouldnt They recalucate pay rate? was told rate never changes but not the same problem, Confused???
