High blood pressure will not trigger the patient to have a fever, if there is a fever, we must consider whether there is inflammation and infection, such as whether there is a recent cold, lung infection, or whether there is any ulceration or abscess formation in a certain part of the body, we must find out the actual cause of the fever, and we can do a blood test, chest X-ray or lung CT examination if necessary. Because many people’s fever may be caused by a lung infection or upper respiratory tract infection, it is important to have the relevant tests done to help make a clearer diagnosis. Common symptoms of high blood pressure are dizziness, headache, panic, palpitations, and some people may experience discomfort such as tightness in the neck. There are also some patients with high blood pressure who may not have any uncomfortable symptoms, but just find out that their blood pressure is abnormal during occasional medical checkups. People like this group of people are more at risk because they have already tolerated high blood pressure, and if they do not have any symptoms, they may trivialize the condition of high blood pressure and not go for active treatment, which may gradually lead to serious problems.
