Hello, I am a 25 year old female, who has been having repeated episodes of feeling like my body is shutting down as if i'm about to black out. These symptoms are in order of how I experienced them a majority of the time. Burning/tingling warm feeling between my eyes traveling to the back of my head. Severe dizziness and a sensation of trembling internally ( out of control) then my vision starts to blurr and I feel as thought I'm going to black out of completely shut down. This began happening 4 months ago. It happened one time back then, here we are 4 months later it began to happen again, with repeated episodes one right after the other. It has happened to me almost every other day if not every day. This is extremely frightening every time it happens. I'm afraid I have a serious medical condition, but the doctors keep telling me it is panic disorder. I don't understand. I only panicked about this after these physical symptoms began and I could not stop them or explain them. I have been to several diff doc now and they keep concluding that it is panic attack I am so frustrated what else can I do?
