The most common cause of headache and face fever is upper respiratory tract infection.1. If you have sneezing and runny nose symptoms, you can take cold medication or antiviral medication. If the temperature rises above 38.5°C, you can take ibuprofen-based antipyretic drugs, which can both relieve headache and reduce fever. 2. Headache and face fever may also be related to elevated blood pressure and increased intracranial pressure. If there is a sudden rise in blood pressure, it may lead to facial congestion and fever symptoms. If the severe headache is accompanied by nausea and vomiting, it may be related to cerebrovascular disease and elevated intracranial pressure. Blood pressure can be measured and head CT tests can be done. High blood pressure can be treated with antihypertensive drugs such as nifedipine. If the intracranial pressure is elevated or there is hemorrhagic cerebrovascular disease, it can be treated with drugs to stop bleeding and drugs to lower intracranial pressure such as mannitol to help relieve the headache as soon as possible.
