If your heat cramps do not improve within an hour of treatment or if your symptoms worsen (headache, dizziness, vomiting and nausea, fainting or a high temperature that’s greater than 104 degrees), seek immediate medical attention.
People who are on a low-sodium diet or who have heart problems should seek medical attention whenever they develop heat cramps.
In severe cases, your healthcare provider will quickly assess your symptoms, take a medical history, and determine the appropriate amount of intravenous (IV) fluids to treat your condition. Adequate rest is also essential to make a full recovery.
