It took me over four (4) years and two denials and finally with a court hearing, a judge and a Benefits Advocate, I won a bench decison which means the Judge decided right there at the hearing, which does'nt happen often. Typically they wait and review the recording of the trial and the medical records and let you know 2 to 6 months after the trial.
Hang in there and don't quit. If you have real issues and truly cannot work, sooner or later you will get it.
