I filed for IU about a month ago. I had already submitted a request for increase for my current dissabilities and the letter states that"Your increase for PTSD and mixed type headaches has already been addressed and will not be addressed in this letter. The letter states that they have requested an exam, but gave no reason or what the exam is for. I have been to 2 different exams in the last 6 months, one was mental health the other was neurological and specifically for my headaches.

What is the reason for another exam? Any advice would be appreciated.

Thanks
Mike
