Sudden coldness in the body of patients with cerebral infarction may be related to changes in temperature, or it may be caused by high fever, seizures, and so on. In terms of treatment, it is mainly to pay attention to keeping warm and applying drugs for the original disease. 1. Temperature change: If the weather suddenly cools down, and family members do not pay attention to adding more clothes or bedding to the patient with cerebral infarction in time, the patient with cerebral infarction is unable to take care of himself because of his mobility problems, resulting in cold stimulation of the body, which may cause sudden chills in the body. Timely addition of clothing or bedding will help to relieve the above symptoms. 2. High fever: If the patient with cerebral infarction has the sequelae of hemiplegia, due to prolonged bed rest, it is very likely to induce pneumonia, which will cause high fever, and may show sudden chills, chills, coughing and other manifestations. You can apply ibuprofen, acetaminophen and other antipyretic drugs, with the application of cefixime, levofloxacin and other antibiotic treatment. 3. Epileptic seizure: If cerebral infarction leads to temporal lobe damage, it is likely to induce secondary epilepsy. When epileptic seizure occurs, some patients may have sensory abnormality, which may show sudden coldness of the body, and may be accompanied by numbness and pain of limbs and other symptoms. Antiepileptic drugs such as carbamazepine and sodium valproate can be applied for treatment. Cerebral infarction patients with sudden coldness, if accompanied by other discomforts, should consult a doctor as soon as possible, after clarifying the cause of the disease, use medication under the guidance of a physician, do not blindly self-medication.
