Foreign body sensation in the throat due to reflux, which usually lasts for half an hour or an hour and can be relieved, often occurs mostly as a characteristic of GERD. Gastroesophageal reflux disease is divided into endoscopy-negative GERD and celiac GERD, and most of the commonly referred to clinical GERD refers to the latter, which is celiac GERD. However, for some people with hypersensitivity of the pharynx and pharyngeal heterosensitivity, called non-erodymic GERD, it can manifest as a strange sensation, itching or foreign body sensation in the pharynx, often as a result of hypersensitivity of the nervous system and disturbance of the plant nerves. Most of them can achieve clinical remission with appropriate symptomatic treatment such as Blue Scutellaria Oral Liquid, Flupirtine Melitrexin Tablets, and Citrus Ice Plum Tablets, while gastroscopy needs to be improved to further clarify the diagnosis.
