I was recently contacted to undergo a PPE following 6 months on TDRL. I was originally found unfit for two conditions from the FPEB, 30% Migraines (Stable) and 70% PTSD (Unstable). I have been scheduled for both a neurology appointment and a psychology appointment. I'm assuming that the neurology is for the Migraine condition. However, if the condition was rated as stable am I supposed to be going for a PPE for that condition? Also, what should I expect at the two PPEs? I currently have a VA rating of 100% PnT that I have had for approximately 4 years. Any insight would be appreciated.
