question: I had my first black out spell last weekend and I was curious to know why it happened. I am a 46 year old female that is currently under doctors care for a undiagnosed illness that maybe either Multiple Sclerosis or Myasthenia Gravis Disease. I had an EEG last year and it showed some unexplained activity that wasn t enough to diagnose me with epilepsy. I feel this strange aura when I feel like I am going to drop. I feel my scalp tingle, my fingers on my left hand tingle, my eyes flutter and I feel like I am in a cold sweat. I have cranial pressure so bad that I feel like my brain will explode. I am scared. I have been having these feelings for over 7 years and I can t seem to get diagnosed or treated
