Why Can't I Stop Sneezing After Septoplasty and Turbinectomy?

Hi, I recently had a septoplasty, turbinectomy and rhinoplasty one month ago. This was because I couldn't breath at night. I'm doing the nasal irrigation flushes everyday as recommended. After the surgery until now which is 3 weeks post op, I find that I sneeze a few times a day which never used to happen. I have moderate eye bags though my eyes do not water. My nose feels sensitive at times. Apparently the whole two turbinates were resected. I'm not allergic to anything. What's going on?
