Whether a fever of 38℃ needs to be injected or not is mainly related to the condition. If you are in a good state of mind, have a good diet, and have normal bowel movements, you can drink more water, which is good for the discharge of sweat and can lower your body temperature. You can put a cool towel on your forehead and swab your armpits, groin, hands and feet. Symptomatic treatment with anti-cold medications, such as cold and flu granules, can treat and relieve the symptoms of fever caused by common and influenza. It can also be treated by proprietary Chinese medicines, such as Pudilan Anti-inflammatory Oral Liquid, Blue Scutellaria Oral Liquid, Shuanghuanglian Oral Liquid and other heat-clearing and detoxifying drugs. If you are depressed and have convulsions, it is recommended to visit the respiratory medicine department or the emergency department, and usually give intravenous fluids for symptomatic treatment. When you have a fever, you should eat a light diet, eat more green vegetables and fruits, and eat less spicy and stimulating, oily food to avoid aggravating your condition.
