Nosebleeds are called nosebleeds in medicine, and there are many reasons for nosebleeds. According to your description, it should be Ritter's blood, the amount of bleeding is generally small, but the number of bleeding makes it characteristic; Epistaxis is a common emergency in rhinology, which is called epistaxis in traditional Chinese medicine and can be divided into local etiology and systemic etiology. Local causes (1) Nasal mucosal ulcer and erosion are common in the anterior inferior area of nasal septum, mostly caused by chronic inflammation. Chemical gas, high temperature and dry air may all be the inducement. In addition, nasal septum spinous process or rectangular process, nasal septum perforation, atrophic rhinitis can also cause local nasal mucosal ulcer, leading to bleeding. (2) Acute infection of nose and sinuses. (3) Trauma: The nasal mucosa is torn due to nasal trauma, which can cause nosebleed. (4) Tumors: Most of the nosebleeds caused by tumors are caused by surface ulceration of tumors themselves, and the degree of bleeding varies with the nature of tumors. Fatal nosebleed can occur when advanced malignant tumor invades large blood vessels. 2. Systemic causes (1) increased venous pressure in the head and neck: seen in chronic bronchitis, emphysema, cor pulmonale, congestive heart failure and other diseases. When the patient coughs, the venous pressure in the head and neck increases, which is easy to rupture the semicircular venous plexus at the back of the inferior nasal passage and cause bleeding. Sometimes elderly patients with constipation can also cause nosebleeds. (2) Increased fragility of vascular wall: seen in arteriosclerosis, lack of vitamins C and K, etc. (3) Hereditary telangiectasia. (4) Obstacle of coagulation mechanism: Any blood disease that affects coagulation mechanism can cause nosebleed, and sometimes nosebleed can be the first symptom of these diseases. Common patients are aplastic anemia, leukemia, thrombocytopenic purpura, allergic purpura, hemophilia and so on. (5) Others: rheumatic fever, acute infectious diseases with high fever (such as typhoid fever and relapsing fever), hyperthyroidism, menstrual epistaxis, etc. Taking aspirin, indomethacin and other non-steroidal anti-inflammatory drugs for a long time will also cause nosebleeds because it will affect the metabolism of arachidonic alcohol and hinder the formation of thromboxane. (6) Rapid changes in air pressure: such as flying, diving or altitude sickness can also cause nosebleeds. Therefore, nosebleeds are the external manifestations of many diseases and pose a great threat to human health and life. We must not take chances and call for attention to health. It is suggested that it is best to go to a standardized otolaryngology department for detailed examination and make a clear diagnosis before treatment.

If the above treatment methods are not ideal, it is better to go to the otolaryngology department of the hospital and find out the reasons before treatment. It can be treated by instruments (such as microwave, DNR low temperature plasma, etc.). ).
