Is a sore and dry throat caused by pharyngitis or gastroesophageal reflux disease (GERD)?
My throat has been particularly dry and painful this afternoon, causing significant discomfort. I would like to ask whether this condition is caused by pharyngitis or reflux esophagitis.

Throat discomfort and dry pain can be caused by various factors, with pharyngitis and reflux esophagitis being two of the more common conditions.
Pharyngitis refers to inflammation of the pharyngeal mucosa, usually caused by bacterial infection or long-term unhealthy lifestyle habits such as smoking and drinking. It mainly presents with sore throat, possibly accompanied by symptoms such as fever, chills, and coughing. Treatment often involves anti-inflammatory medications like amoxicillin capsules, and may also include syndrome differentiation treatment in traditional Chinese medicine. Reflux esophagitis is an inflammatory condition caused by the backflow of stomach acid or bile into the esophagus, irritating the esophageal mucosa. In addition to throat discomfort and dry pain, patients may also experience symptoms such as retrosternal burning sensation (commonly known as "heartburn"), belching, and acid regurgitation. Symptoms may worsen when lying flat at night. If left untreated for a prolonged period, it can lead to damage of the esophageal mucosa and even serious complications such as Barrett's esophagus. Treatment methods include pharmacotherapy, such as omeprazole enteric-coated capsules, and general measures such as elevating the head of the bed and avoiding eating before bedtime.
Accurate differentiation between the two conditions requires a comprehensive assessment incorporating medical history, clinical manifestations, and necessary examinations such as laryngoscopy and gastroscopy.
