The most common cause of sore throat and coughing up bloody phlegm is inflammation of the throat. When inflammation of the throat occurs, there will be congestion and edema in the throat, and a large amount of inflammatory exudate will be secreted, and phlegm will be formed. Because of congestion and edema, blood cells will also be exuded, and the symptom of coughing up blood sputum will occur. Whenever there is accompanying inflammation, there will be redness, swelling, and heat, so there will be a sore throat. If it is indeed caused by pharyngitis, anti-inflammatory drugs can be used to relieve it, and it is recommended to take Pudilan Anti-inflammatory Oral Liquid or Blue Scutellaria Oral Liquid orally. In case of bacterial infection, oral antibiotics, such as penicillin, are also needed. If there is no allergy, amoxicillin or amoxicillin clavulanic acid potassium can be used. In addition, it needs to be examined by an ENT doctor, and if there is no inflammatory condition, pain and coughing up bloody sputum caused by tumors in the throat need to be excluded.
