I receive ptsd disability. What is the prognosis for this. I was rated at 60%. Will I have to go through c&p exams periodically. Is the percentage for the rest of my life or can it change? Am I required to be re-evaluated periodically. I attend group forums but nothing documented or official. I want no help from the government but will I be required to get treatment from them even though I don't want it from them. From what I have read for the most part ptsd is never really cured. that is why I wonder if the % you are awarded can flucuate with the symptoms.
