Colds, coughs and nosebleeds are most likely caused by infections in the nasal passages and inflammation of the throat and trachea, which can lead to coughs and nosebleeds. When inflammation occurs in the nasal cavity, there will be congestion and edema, and due to the influence of inflammation, the symptoms of nosebleeds can easily occur. Inflammation of the pharynx is characterized by a strong irritation, accompanied by inflammation, redness, swelling, heat and pain, as well as the secretion of a large amount of inflammatory exudate, which can irritate the throat and lead to coughing. Inflammation of the trachea also secretes a large amount of inflammatory exudate, which constantly irritates the mucous membrane of the trachea, leading to coughing. Effective antiviral or antibacterial treatment for colds is more effective at this time. For example, in the early stages of a cold, viral infections are more common, and you can take Pudilan Anti-inflammatory Oral Liquid orally. In the later stages of a cold, bacterial infections are more common and need to be treated with antibiotics, such as cefixime. If the effect is not good, you need to go to the ENT department to do a specific examination of the nasal cavity, but also to check the coagulation function is not abnormal.
