Is this normal? what could it be?
I was cooking lunch for my family when I suddenly felt dizzy, my head pulsed, my ears rang like crazy, I felt really hot, and my vision suddenly darkened like circles and it was pixilated. After that, I fell to my knees but tried to keep going by shoving myself to the sink and drinking water but stomach churned and I felt like I could throw up. I tried to sing to myself or walk or continue making lunch but it wouldn't go away and I just couldn't. I saw in the mirror that I was extremely pale. This entire thing lasted about 5-7 minutes and for like 7 minutes later my body (but mostly my hands) shook insanely. I know that if I had sat down as everything was happening I would have passed out.
So, is this normal? What could it be? Is it something I should tell the doctor about or just go on with life??
