How long it takes to recover from a foreign body in the throat depends on the specific disease.
In the case of acute pharyngitis, with effective treatment, the symptoms can be relieved in 1 to 2 weeks and the foreign body sensation will not last too long.
If the nasopharynx is structurally abnormal, such as enlarged tonsils, the foreign body sensation can disappear after surgical treatment and care.
If the problem is caused by gastroesophageal reflux, it may require lifestyle adjustments and acid suppression therapy to make the foreign body sensation go away.
