If you get heat cramps, how do you feel?

Tied, muscle pain: Heat cramps can result in intense tightening of the muscle for seconds to minutes and are often very painful. Immediate treatment involves resting the affected area, gentle stretching of the muscle (if possible) and hydration. Many, but not all, cramps are related to dehydration and/or sodium/potassium depletion. After cramps, many feel very fatigued, thirsty and those muscles become sore.
