Reflux pharyngitis occurs when the stomach acid is excessive, the gastric cardia sphincter relaxes, and the stomach contents reflux into the esophagus, which in turn causes some erosion of the pharynx, so inflammation of the throat can occur. It can manifest as pain in the throat. The pain is often related to sleep, for example, it is more severe in the morning and the symptoms can be naturally reduced or relieved in the afternoon. The use of drugs for throat inflammation is not effective, you can use drugs for stomach problems, such as the use of acid-suppressing and pain-relieving drugs omeprazole enteric capsules, pantoprazole, etc., can achieve satisfactory results.
