The appearance of yellow phlegm in the uncomfortable throat is due to the occurrence of bacterial infection in the throat, which leads to the condition of pharyngitis. Once pharyngitis occurs, the throat will be congested and edematous, and it will also be accompanied by redness, swelling, heat, and pain, so you will feel uncomfortable in the throat. Because of the inflammation, the throat will secrete an inflammatory mixture. Neutrophils will gather in the throat and phagocytose foreign bacteria, and then the neutrophils will undergo lysis and necrosis, and mix with the inflammatory exudate to form yellow sputum. The yellow sputum needs to be treated with antibiotics. For throat infections, the more effective antibiotics are cephalosporin antibiotics or amoxicillin. You can also take buspirone anti-inflammatory oral solution, which has both anti-viral and anti-bacterial properties, and the anti-inflammatory effect is also particularly strong to relieve throat discomfort.
