Pharyngitis does not cause chest pain and does not lead to other systemic symptoms, mainly abnormal sensations in the throat, such as foreign body sensation, itching, and slight pain, which will be obvious when swallowing saliva, but not when swallowing food, and the location is mostly variable. However, a very important factor causing pharyngitis is acid reflux, which can lead to a burning pain sensation behind the sternum with a linear distribution and requires a combination of laryngoscopy as well as gastroscopy to further confirm the diagnosis. If nausea and acid reflux symptoms are usually present, this can also be further determined. After excluding organic lesions, such as tumors, you can choose to use drugs to inhibit stomach acid and promote gastrointestinal tract motility, quit smoking and alcohol, reduce the consumption of spicy and stimulating foods, and eat more fresh vegetables and fruits.
