Patients with fever may experience nosebleeds, mostly due to the loss of water in the body caused by fever, which eventually causes a dry throat and dry nose, and ruptured blood vessels in the nasal mucosa. In the case of external wind-heat, which is also known as fire, the person will experience high fever, headache, sweating, sore and red throat, yellow runny nose, red tongue with yellow coating, etc. In severe cases, nosebleeds will occur. The main cause is the attack of external wind-heat evil, resulting in the loss of lung purification. In this case, you can drink some Banlangen granules or Xiasanju granules. Of course, you can also take some oral medicine such as Yin Qiao Detoxification Tablets, Niu Huang Detoxification Tablets, Anti-Viral Oral Liquid, etc. In addition to the common cold, some cardiovascular diseases may also cause fever and nosebleeds. For example, patients with hypertension, when combined with acute infectious diseases such as lung infections, may have some stress reactions such as nosebleeds, upper gastrointestinal bleeding, or even brain bleeding if their blood pressure is not well controlled. Therefore, fever and nosebleed is only an external manifestation of the disease, and the key to treatment is to find the cause and treat the disease that causes this symptom. When a patient has fever and nosebleed, the first thing you can do is to look at the nasal mucosa through ENT rhinoscopy to see if there is any blood vessel rupture, and if there is blood vessel rupture, you should promptly compress the blood vessel fissure locally and use hemostatic drugs. In addition, the underlying diseases of hypertension and coronary heart disease need to be excluded.
