While under care of WC Dr for knee injury in 3/10, injured lower back in 5/11, during work conditioning, that he prescribed. Can or should I be able to collect more that 104 weeks of PD and/or SDI (because SDI is $200 less than my PD weekly benefit, so I'm owed the difference from WC Ins I'm told)? WC stopped paying, returned me to work, I didn't go, and hired an atty. But this has never been mentioned to me, and he dsnt seem to know the answer. So I collected about 10 mths of WC, and then 52 weeks of state disability. So, is there anything left, having had 2 different injuries, to 2 different body parts, and 2 different times??? In addition, WC only paid for 1 month, for the back injury, then they disputed it. But Ortho QME has since given me 1 yr retro time off from 11/11 - 11/12. So?
