What Does a Thyroid Storm Feel Like?

A thyroid storm feels like an overwhelming combination of rapid heart rate, extreme anxiety, and severe overheating. Your heart may race, and you may have heavy sweating, trembling, severe restlessness, or a high fever. Symptoms vary, and thyroid storm can occur without a heart rate above 140 beats per minute or a temperature of 104°F. Seek emergency medical care for suspected thyroid storm rather than waiting for specific numbers. Additional symptoms include nausea, vomiting, confusion, and extreme fatigue despite feeling wired. This is a rare complication of hyperthyroidism, but it requires immediate emergency treatment because it can be life-threatening.
