Hi Pat,
My case was also a WC case, and under the advise of some old friends at BT, I went to the library and took out a book called " Nolo's Guide to Social Security". This was a tremendous help, followed it to the " T " and was approved in 6 weeks without the cost of a lawyer.
I know everyone/ every case is different but before I spend money on a SS lawyer who will take their cut, I'd at least look over this book. Oh, I also applied during my WC case as one really had nothing to do with the other except for the fact I could no longer work. My two cents, hope it helps
