Definitely apply for social security.... they approved me in three months.... I was shocked. Apparently they are pushing through things related to PTSD and MST. just sign a release for them to get your medical records. They even back dated it for a year for me because i had not worked in the last year.... got a nice lump sum check and get 1200.00/mo from SSI based on my previous income payments into social security. Wish the VA worked as fast and efficiently as they did.
