Why am I still having these symptoms after septoplasty?

I had septoplasty one month ago due to repeated sinus infections cold symptoms muscles aches and extream fatigue. After surgery I can see very slow improvement. Less dizziness ànd fatigue but frequent sore throat, ear tightness all the time. No more blood and crust now but when I blow my nose some green thick mucus with dark bloody crust come. I HV dirty foul smell, still feel lightheadness sometimes. Asked my surgeon he said f9. My Improvement is OK? How much time it will take fully recovered.
