The causes of head swelling after the fever has gone away include poor rest and the presence of infection.
1. Poor rest: If the patient does not rest well during the fever, nervous tension or excessive anxiety may cause tension headache, which is manifested as swelling and pain or pressure in the head.
2. Infection
The pathogen causing the fever spreads to the skull and causes encephalitis or meningitis, which can also lead to head swelling and pain.
If the pathogen causing the fever spreads to the sinuses and the sinuses become infected, the patient may experience persistent nasal congestion, runny nose, and pain in the frontal area or the base of the skull and the occipital area, which is mostly characterized by swelling and pain, and may be accompanied by pressure. The sinuses are divided into four groups, and the different groups of infected sinuses will cause headaches in correspondingly different locations.
If the headache persists after the fever goes down, please go to the regular hospital for diagnosis and treatment, so as not to delay the condition.
