I had sinus surgery almost 7 weeks ago. Should I still feel like my sinuses are swollen?

The type of surgery I had was Septoplasty, Turbinate Reduction and Concha Bulloosa surgery I feel somewhat better but I am still feeling congested. Not a lot of mucus but just a pressure feeling in my sinuses on the sides of my nostrils. I am doing nasal rinses twice a day, and just started back on Flonase and Astelin. Is it normal to still feel congested at times? Seems to get worse with extreme temperature changes such as coming from outdoors into the cold air conditioning.
