Full body cramp. Junior year in high school I was at a football workout in the summer and I only got one water break for a 2 hour practice in 90 degree weather. I was fine until the next day after practice. The team was in the weight room and we were wrapping up practice and all of the sudden, both of my calves start cramping at the same time. Next came my thighs, hips, obliques, arms, chest, and neck. Basically all the big muscles in my body started cramping from the bottom up. The trainer put me in the shower under cold water with all my clothes on and I kept drinking water until I couldn't drink anymore. Any time I tried to get up, the cramps would just get worse. It got to the point where I had to be carried out to my moms car to be taken to the medical clinic across the street but they couldn't do anything so they called an ambulance. On the way to the clinic I was cursing in front of my mom from the pain, something I never do. I actually shit myself from how much pain I was in. On the way to the hospital in the ambulance, the cramps stopped completely and I had to ask the driver to stop so I could piss because of all the water and IV fluid in me. I couldn't really walk the rest of the day and I had to spend a night at the hospital. I suffered from heat exhaustion and a full body cramp due to be dehydrated. To this day, I always stay hydrated when exercising because that full body cramp was the most excruciating pain I have ever felt. It was like being stabbed in all of your large muscles in your body.
