Numbness in the head and feet should first be considered as a result of cardiovascular disease, such as coronary artery blockage, atherosclerosis, heart failure and other causes of symptoms, and may also be due to the presence of nerve paralysis or neuritis and other symptoms. It is also important to consider whether the condition is due to traumatic injury to the nerves, such as numbness due to sciatica caused by a herniated lumbar disc. Numbness may also occur due to vasospasm in the brain caused by the patient’s cervical spondylosis, and symptoms caused by fever or allergic infection cannot be ruled out. Patients should pay attention to their living habits in daily life, avoid emotional excesses that lead to increased blood pressure, and pay attention to their condition and go to the hospital for early diagnosis to avoid other complications.
