This symptom, which hurts when pressed next to the nostril, is a pain caused by localized follicular infection, and then it is caused by nasal vestibulitis, which is not much of a problem. In the early stages of symptoms, you can use anti-inflammatory ointment, such as Bactrim or Erythromycin eye ointment, applied topically. If you can’t control it with conservative medication, you need to use antibiotics orally or infusion to treat the symptoms, and it is recommended to choose cephalosporin anti-inflammatory drugs. Because the blood vessels around the nose do not have venous valves, bacteria can easily retrograde to the cranial area, and hair follicle infections in this location should never be squeezed to prevent retrograde infection of bacteria. For inflammation inside the nose, you can also use saline or physiological seawater to rinse the nasal cavity, which can also achieve a clean and anti-inflammatory effect.
