(Concern) Will my chronic rhinitis treatment be effective??

Hello, my health concern for this event is chronic rhinitis. I have been living with rhinitis for a long time, but it worsened significantly during the recent COVID-19 pandemic. It was just a runny nose at first, but afterward, I experienced severe sneezing and a significant loss of smell, making it impossible to taste food. At first, I thought it was a post-COVID symptom, but when I went to the hospital, I was told that it was due to chronic sinusitis and sinus infection, which made it difficult to smell. I am currently undergoing medication treatment, and I am really curious and worried whether the sinus infection can be completely cured if I take the medication consistently. I really want to get rid of my rhinitis.
