I either get somewhere between  1-4 of these "spells" every year.  where first, my ears  "pop" and ring. I  won't be able to hear out of them at all.  It is a constant, very loud ringing. 

Second, my eyes start to get black spots. And eventually I won't be able to see anything. It's all completely black.  

 

Third, I get extremely dizzy, I am not able to do anything, I shake and my body temperature switches very quickly to extremely hot to freezing cold about every 30-45 seconds, then my temp changes happens about every minute or two after. 

 

 

The first time this happened to me was when I was taking my final exam in Spanish. It lasted from the beginning of the exam to the very end, which was 3 hours. I didn't finish the exam. I just sat there loosing my mind because I couldn't see or hear and I didn't know what to do.  

 

The second time this happened when I was with my sister, and cousins getting something for my moms 50th birthday (which was on that day). We were in a store and it started. I apparently was in the middle of the isle on the ground and I couldn't respond. My sister took me to her house and I slept for a few hours. Still felt dizzy and out of it at the party. 

 

Another time it happened I was in school writing a paper . I was excited to write this paper because I enjoyed the book the paper was based off of, so this isn't stress related I don't think. My teacher tried to ask me something but I didn't respond. I sat there for the whole class. Symptoms getting worse. Apparently the school nurse came and saw me. I don't remember what happened after. 

 

The next time this happened I was in another class. The ears popped and my vision started to leave me. I got very nervous as the class was about to be dismissed and there would be tons of students.  I was very flustered and afterwards I stumbled to my math room and told my teacher I felt like I was going to pass out with whatever time I had left to somewhat see and hear. I told her this has happened before. She had my friend take me down the stairs and to the nurses office. Turns out the nurses office was locked and no nurse in sight. By that time my ears had begun to ring and my vision was almost completely gone. All I remember and heard after that was "counselor" and "called mom". I was escorted outside and I took all my coat and sweatshirt off (it was 25 degrees outside according to my mother) trying to cool off. By the time it took my mom to get to the school (10 minutes) i was still hot. We went home and I was freezing, layering myself in fleece clothes and blankets. . I woke up hours later with a 99.5 temp. I was still freezing cold so I took a bath. Then I had diahrreah. I Woke up the next morning, sat up, boom- head felt like a hundred pounds, headache, hot, dizzy, ears ringing.

 

 These spells last a very long time, from anywhere between 1-3 hours or even overnight.  I have had 1-4 of these experiences every year, they happen at random. Anyone know what is wrong with me? They are terrifying.
