Give you some advice based on personal experience, for reference only:
When I was a child, my nose was seriously injured, which led to deviation of the nasal septum. I didn't have an operation until a year ago. I used to think it was nothing. Until a year ago, I was particularly serious and had difficulty breathing. I had to breathe through my mouth, and then I went to a professional otolaryngology hospital for surgery. I'm much better now. Deviation of nasal septum is a physical nasal deformity. It is impossible to recover by medicine or itself. The best way is surgery. If your age is appropriate, surgery is recommended. Otherwise, problems such as frequent nosebleeds, dyspnea and headaches caused by deviated nasal septum will plague later life.
