I had to stop work in 1995 due to ptsd but just recently was given70% sc ptsd which was then added to my already receiving 40% sc for physical problems when I got out of the navy in 1972. In nov 09 when they added the 70% for ptsd and 40% for physical they came up up with 80%. So I filled out a form 21-8940 for individual unemployability and havent worked since 1995. so now they have me scheduled for a ptsd exam by the same doctor that gave me 70% in nov this year. I dont know if I should appeal the first decision to give me 70% or just wait to see about the IU. Any help from you learned fellows on here would be of great help. In the past have put in for ptsd but this was the first time that they gave me mental exam even though I have been seeing a va doctor for my ptsd for many years..all the way back to 1972....HELP ME please....
