Nosebleed

Nosebleed (epistaxis), also known as epistaxis, is one of the common clinical symptoms, mostly caused by nasal cavity disease, but also caused by systemic diseases, occasionally bleeding from nasal cavity due to bleeding near the nasal cavity. Nasal bleeding is mostly unilateral or bilateral; it can be intermittent and repeated bleeding, and it can continue to bleed; the amount of bleeding varies, with only slight blood in the snot, and severe cases can cause hemorrhagic shock; repeated bleeding can cause anemia. Most bleeding can stop on its own.
