In women, a fever in the back, like a fire, may be related to phytodysfunction, which is more common during perimenopause, when the hormone levels in the body are disturbed, and sometimes the patient may also have phytodysfunction. In addition, a thyroid function test should be performed to clarify this. If hyperthyroidism is present, fever, irritability and panic may also be present. It is recommended to measure the body temperature during the attack to see if it is high, and to measure the thyroid function to see if there is hyperthyroidism. If similar conditions occur repeatedly, it is recommended to go to the hospital to improve the relevant medical examination for clarification.
