I've been expierencing some bad pains in my stomach. I was due for my period a couple days ago. This morning i woke up at 5:30 and went downstairs to take some advil because the pain was unbearable. I went back to bed, woke up around 7:30 and went to the bathroom. I was sitting on the toilet with the trashcan on my legs. A few moments later i started expierencing clamyness on my forehead, blurryish vision, and my ears were clogging up as if i had swimmers ear? I went back to my bedroom to get water but when i went to go grab the bottle my vision went black and i was feeling around for it as if i was blind. I gained it back in a few short moments. I went back to the bathroom but then i passed out or fainted? I didn't realize I even fell. The after that I put some food in my stomach and had diarrhea. What's wrong?
