Hello. Since about 8 years old, I would get these events where I would get these strange symptoms. We will call these episodes. The episode generally comes along when I go to a place I am very farmiliar with(Like my house and school) but on a rare occasion it can happen at places I have never been to before. During these episodes, I will start by feeling very nauseous, then feel very hot In the face. The strangest symptom is I will get intense dejavu, even at places I have never been to before. The only thing that seems to help is using the restroom. I came back negetive for epilepsy, and migranes, so my doctors are stumped. Any ideas what it may be?
