The common causes of headache, dizziness and foot weakness in patients should be considered to be caused by diseases such as cold and fever. If patients are accompanied by muscle aches, cough, nasal congestion and runny nose, they should pay attention to their body temperature for measurement. Patients with headache, dizziness and weak feet may be caused by atherosclerosis of the cerebral arteries if they are elderly. Atherosclerosis of the cerebral arteries will lead to a decrease in the elasticity of the cerebral blood vessels, and the blood vessels will be in a narrow state, resulting in poor cerebral blood flow. . There are also symptoms of headache and dizziness in some patients, which may be related to mental disorders, such as patients with anxiety and depression problems, also prone to somatization symptoms such as headache, dizziness and foot weakness.
