The patient’s nose is painful and then swollen. Clinically, the following causes are mainly considered: First, the patient’s nose may have been traumatized, resulting in a fracture of the nasal bone or nasal septum cartilage so it will be painful and the nasal mucosa will be swollen. In the treatment, it is recommended to improve the CT of the nose and then actively anti-inflammatory and anti-swelling. Secondly, the main consideration is the formation of boils in the nasal cavity, because patients usually do not pay attention to hand hygiene, often picking the nostrils with their hands, so the mucous membrane infection will form boils. In severe cases, the patient may even have fever and unbearable pain. It is suggested that the patient can go to the hospital for active examination, and if necessary, you can administer antibiotics, commonly used is cefuroxime sodium injection, and after active treatment the patient will have significant improvement in pain and then swelling inside the nose.
