When a patient develops pharyngitis, further symptoms such as coughing with blood in the sputum or blood clots are often related to the inflammatory disease state of the pharyngeal mucosa. Inflammatory diseases can cause the mucous membrane of the pharynx to become congested and swollen to varying degrees, and there may be some dryness and other manifestations. In addition, some patients may also use their voices excessively, smoke, drink alcohol, eat spicy and irritating food and other factors, leading to further aggravation of pharyngitis symptoms, which may easily lead to coughing and bleeding symptoms. If bleeding symptoms recur or worsen further, careful and comprehensive examination of the entire respiratory tract and even the digestive tract is required.
