The patient’s nostrils are often painful when pressed for the following reasons: 1. The patient may have been traumatized, for example, after the nose has been hit by external forces, there may be collapse of the cartilage of the nose, sometimes the pain is more obvious, and the soft tissues may also be accompanied by contusions, the patient may also have pain when pressing the nostrils for a short time after nose surgery, because the surgical area has not completely recovered. 2. If the patient often picks the nostrils with his hands or plucks nasal hairs, it will lead to painful nasal mucosa infection. 3. Consider that the boils are formed inside the nostrils after the patient is anxious, on fire or under pressure, and if the infection is very serious, the patient will have more obvious pain.
