Introduction
Sore throat accompanied by excessive salivation may indicate pharyngeal ulcers—worsened oral ulcers—resulting from deficiencies in vitamin B or vitamin C, bacterial or viral infections, or pharyngeal trauma. It may also stem from acute pharyngitis caused by bacterial or viral infections, wherein swallowing triggers both throat pain and increased salivation. Additionally, gastroesophageal reflux disease (GERD) can cause sore throat and excessive salivation due to corrosive irritation of the pharyngeal mucosa by refluxed gastric contents.

Sore throat and drooling may be caused by conditions such as throat ulcers, acute pharyngitis, or reflux esophagitis.

1. Throat Ulcer

A sore throat accompanied by drooling may result from throat ulcers, which typically occur when oral ulcers worsen and extend to the mucous membranes of the pharynx. These ulcers can also be caused by deficiencies in vitamin B or vitamin C, bacterial or viral infections, or injury to the throat.

2. Acute Pharyngitis

Drooling with a sore throat may also stem from acute pharyngitis caused by microbial infections such as bacteria or viruses. In affected patients, the pharyngeal mucosa commonly exhibits inflammatory responses like bleeding and swelling. Swallowing saliva may press on the swollen areas, leading to pain and drooling.

3. Reflux Esophagitis

If a patient has reflux esophagitis, they may also experience a sore throat and drooling. This usually occurs when gastric contents or stomach acid flow back through the esophagus into the throat, irritating and eroding the pharyngeal mucosa. This condition may also be accompanied by symptoms such as belching and heartburn.
