hello ronan,
I am not an expert but I have been in the postal system since My first injury in 1998, back when OWCP wasn't so overwhelmed, and that's why these denials are going on. My injury has caused me to have multiple surgeries and I followed restrictions and did the assignments usps gave me, always a trooper. Now I am going on 20yrs...and I went thru the reasessment program and accepted an offer to change my craft, mind you they said it would be within my restrictions..turns out I am suffering again. And I after an accepted condition, and a PAID scheduled award of the loss of my extremities , am going thru it again, was LWOP for 7 weeks! They denied my claim because they couldn't understand how my new jod caused a reoccurance of my original ACCEPTED, WITH THEIR OWN SECOND OPION DR.,had happened. I know this sounds like over kill but I hired an ATTNY. his name is Alan Shapiro to handle this for me because of OWCP's situation. You stand a better chance to have a lawyer fight for you, he has a web site I suggest you do this his fee is 20% of what you get, I am on 4 hr works days after 20yrs with LWOP every day..jump on it
