I hope this makes sense. I was rated 10 percent for left knee patellofemoral chondromylacia and 30 percent depression secondary to knee condition, this was in 07. I recently applied for increased rating of depression and bilateral hearing loss with tinnitis. I went to my QTC exams and also filled out the paperwork they sent me and returned it. Now a few weeks ago I received another pile of papers to fill out talking about individual unemployability. My question is what in tdui and does this take the place of my increased rating request or do they go together. I've tried to talk to my RSO about it but can't get through to him I know they are busy, so I thought I would ask for help here. thanks in advance.
