May need a revision of your septorhinoplasty
It is possible that your septoplasty was under corrected or you have a recurrence of turbinate hypertrophy. In any event you will need to have an internal nasal examination to determine the extent of your problem. It is also possible that you are experiencing a degree of collapse of the internal nasal valve.
taylor1994, the first thing I would advise is for you to make an appointment with the your surgeon and discuss these issues. should you've find this visit to be unhelpful then I would suggest you would obtain a copy of your photos and operative note and see several facial plastics specialist. Make sure they have at least 10 years of experience. Make sure you check out their website before the visit to see if you like there pre-and postoperative photos. Good luck!
You should either return to see your surgeon and/or seek a second opinion from another experienced rhinoplasty surgeon. There are so many variables and so much information that is not available here that it is impossible to give meaningful advice other than that.
