fainting

[bernie16]

no warning  just all of sudden cold chills that lasted all day and fainted later on that evening

Cold chills can come from having the flu, or perhaps in your case with the fainting, could be something as simple as you not having enough protein to eat on a regular basis.  Protein is like the wood in a fire, it burns and heats up a person.  And if you ain't got no fire, you'll get cold.  In addition, protein gives you energy, and if you don't have any, you can get pretty weak and light-headed.  But there are many reasons why this happened to you, those are just my top two choices.  Neurologically speaking, I personally cannot think of anything along those lines that would make you have chills and pass out.  For example, if you had a seizure, instead of getting cold, you would seize up and then pass out.  Perhaps a different field of medicine is at work, like being sick, as I mentioned before, or maybe a cardiology abnormality, which has to do with the blood circulation in the body, may be what gave you chills and made you feel faint.

I have had the flu for approximately a week now and i haven't had the flu since high school. I'm 24 in January. Last night I was burning up like never before and I decided to switch the fan on to cool down, but I never got that far as I fainted / blacked out. I generally have high body temperature when healthy too. I do eat and drink, but I seem to not be able to sleep enough. Could this just be my body not being used to having the flu or could something else be wrong? I constantly suffer from sinus headaches and I think my body temperature is making it worse as it feels like it pulsing like my heart. Please advise...
