My mom always feels some irritation in her throat. Why?

Hi,

Welcome to icliniq.com.

Feeling something stuck in throat like foreign body sensation is common in females and is called as globus pharyngis (some constant feeling of obstruction in throat). It is very common and nothing much to worry. It is supposed to be caused due to acidity and gastric reflux. What you can understand is that the acid from stomach comes into throat and it causes burn and swelling. This swelling will be felt as something is there. So, she can forget about it. My advice is to relax and avoid stress. If she alter her diet and follow some lifestyle changes including any acids, then she will be fine. But, remember, it is difficult to totally get rid of this sensation as it is difficult for females to stop worrying and take stress. We also have to rule out any malignancy in throat in such conditions. As her endoscopy is normal nothing to worry about.
