I had been skiing for about 2 hours when I decided to break for lunch. The first sign that something was wrong was that my legs felt like burning jelly. Not because I was tired, but because of something else. After I'd gotten my food and had settled down, I began to eat. Ten minutes in, my head began to swim. A burning pain settled in on my upper chest, and I started choking. I decided I needed to lie down, but there was no good place. Then, it got worse.
The pain intensified, and I lost my legs. Not literally, but I couldn't feel them. Even though my eyes were open, I could barely see anything through black and red spots. I panicked, and began to slip off my bar stool (a.k.a. collapsed into the nearest person's arms). After that, I was lowered onto the floor and given some water. Someone called the medics, and they came with an oxygen tank.
They decided that my collapse was most caused because:
a): I was extremely dehydrated, having forgotten my water bottle at the hotel.
b): I had Level 3 (out of 5) altitude sickness.
c): I had fallen a lot while skiing, and though I was wearing a helmet, my skull had probably sustained some wear and tear of some sort.
d): My boots and socks were one size too small, so I had cut off a lot of my blood flow from my feet.
They gave me oxygen for about ten minutes, asked me some questions, and that was it!
