Trouble breathing even after septoplasty

I recently had septoplasty surgery for correcting the deviated septum. I was very hopeful that after this I will be able to breathe properly and have life changing benefits. But it's been 3 weeks since my surgery but my breathing is the same as before. When the suture was removed one week after surgery, I felt like my airways had been widened and felt well. The surgeon suggested doing saline nasal wash and using nasal spray for one month. I don't feel any pain or swelling in the surgical area or anywhere in the nose. But I sometimes can't take full breath due to which I'm often tired, lack concentration and poor sleep like it was before. The surgeon said that I should visit her only if there is any complication. What should I do? Can I still hope for an improvement in breathing in the upcoming weeks or months. I'm so disappointed and demotivated as I wanted to live life to its full potential ..😓😓 I'm attaching my discharge summary herewith.
