I was initially rated at 30% for PTSD after I got back from Iraq in 2004. The VA psychiatrist wrote up the evaluation like a 50% rating, so I appealed to the BVA. The BVA agreed with me and just raised my rating to 50%. Now I'm worried that the VA will try to periodically re-evaluate me to lower it to 30% or lower. Do they typically do this? I know that having the last VA eval certainly raised my stress level, and I'd like to avoid that. Thanks in advance.
