Nasal inflammation: Nonspecific inflammation of nasal cavity and paranasal sinuses, such as acute rhinitis, atrophic rhinitis and sinusitis, is a common cause of bloody mucus in nasal cavity. The common cold, due to congestion and swelling of nasal mucosa, coupled with secondary infection, leads to nosebleeds when blowing nose, which is caused by the rupture of capillaries, and disappears automatically with the cure of rhinitis and the improvement of nasal ventilation function. Special working environment: Long-term exposure to dry and dusty working environment will easily lead to dry and broken nasal mucosa, easy bleeding and nosebleeds. Working in an environment where chemicals such as mercury, phosphorus and arsenic volatilize for a long time can also lead to nose bleeding. Some specific inflammation, such as tuberculosis, syphilis, malignant granuloma and other infections, can cause the dilation of small blood vessels in the nasal cavity or the erosion of nasal mucosa, leading to epistaxis. Systemic etiology: nutritional disorders or vitamin C deficiency, cardiovascular diseases, blood diseases, etc. can cause bloody nose. Systemic diseases with coagulation dysfunction or vascular fragility can cause bloody nose. Such as leukemia, hemorrhagic purpura, aplastic anemia, hypertension, pulmonary heart disease, vitamin C, B2, phosphorus and potassium deficiency, rheumatic fever, chronic diseases such as liver, spleen and kidney, acute infectious diseases, etc. Foreign body in nasal cavity: If the child's unilateral nasal obstruction is accompanied by bloody purulent nose, it is generally considered to be caused by foreign body in nasal cavity. Many children, because of their curiosity, stuffed foreign objects such as beans and paper balls into their nostrils. They are afraid of their parents' criticism and dare not speak, so they dig for themselves. Results The foreign body stayed in the nasal cavity for a long time, which stimulated the nasal mucosa and led to the ulceration and bleeding of the nasal mucosa. Female menstrual period: some women have periodic and regular nosebleeds before menstruation or 0 ~ 2 days after menstruation, which may be accompanied by less menstrual flow or no menstruation, which is related to the changes of estrogen secretion during female menstrual period. Nasopharyngeal carcinoma: Nasopharyngeal carcinoma is one of the most common tumors in China. Among the head and neck malignant tumors, the incidence of this disease ranks first, and the onset age is mostly between 40 and 60 years old, with more males than females. Its main manifestations are: bloody nose or bloody nose, which is mainly caused by the rupture of tumor surface, and the amount of bleeding is generally small, especially when getting up in the morning. Because of less bleeding, it is often ignored by patients or treated as respiratory inflammation. Nasal cavity tumors: benign tumors include nasopharyngeal fibroangioma, papilloma or polyp infection and necrosis, while malignant tumors of nasal cavity and paranasal sinuses include squamous epithelial carcinoma, adenocarcinoma and sarcoma. Most of the nosebleeds caused by tumors are caused by surface ulcers of the tumors themselves. Benign tumors only have blood in the nose, and the amount is not much. The early manifestations of malignant tumor are unilateral progressive nasal congestion and nosebleeds, and gradually frequent bleeding, and severe nosebleeds can occur when large blood vessels are damaged. Due to bone destruction in the later stage, purulent nosebleed may occur, accompanied by severe headache, so be vigilant.
I suggest you go to the hospital to find the cause and treat the symptoms. I wish you a speedy recovery!
