There are many reasons for the swelling of the temples, which cannot be generalized. Usually, when the patient is fatigued, it can cause vasospasm of the skin at the temples, resulting in abnormal expansion or pulsation of the blood vessels, which induces swelling of the temples. This situation is a normal reaction, which usually requires no special treatment and can be relieved by massaging the temples and resting with proper eye closure. But if the patient bilateral temples swelling for a long time, may be related to the following diseases: 1, primary headache: such patients are mostly caused by anxiety, tension, neurological disorders, such as persistent head dull pain, the brain can produce tightness, radiation to the temples can cause bilateral temple swelling, accompanied by tinnitus, panic and shortness of breath and other symptoms, but no organic lesions, in serious cases can cause insomnia, depression, etc.; 2 The patient’s intracranial blood pressure is elevated, which can cause vasodilatation of the head and face, and when the brain is congested, it can cause swelling and pain in both temples. Patients are advised to measure their own blood pressure at home, and if the value is greater than 140/90 mmHg, they should seek medical attention to determine the presence of such diseases; 3, cerebrovascular organic diseases: cerebral hemorrhage, cerebral infarction, subarachnoid hemorrhage and other cerebrovascular organic lesions can cause obstruction of blood flow in the brain, resulting in increased intracranial pressure, which causes bilateral temple swelling. Patients with these diseases may also suffer from nausea, vomiting and even impaired consciousness. If similar symptoms are detected, a CT brain examination should be performed at the hospital to clarify the cause. In addition to the above-mentioned common conditions, cold, rhinitis, gastrointestinal inflammation, etc. can also cause bilateral temple swelling, and patients need to further differentiate according to the accompanying symptoms, and if they are unable to determine, they can seek timely medical attention to clarify the diagnosis.
