Depending on how bad it is for you, I can recommend thinking about turbinectomy. Had it done due to chronic, allergy related swellings, and it was life changing.
do you still have any symptoms? I had a turbinate reduction and septum surgery last year, it's helped but I still need sprays in the morning and night and pills for the allergies.
It basically means surgically removing parts of your chronically enlarged/swollen turbinates so that your airways are free again. Along with that I've had a nasal spur removed (slightly blocked airways); Septumplastic (had a slightly deviated septum that also inhibited airflow a bit); and while at it the ENT also recommended and did FESS (Opening/Widening some paths to the sinuses).
It was a pretty life changing surgery that finally allowed me to properly sleep again, and do exercises/run while breathing through the nose. For some people, the turbinates may become enlarged again after a while, but for me it's been great for two years already.
Have you considered just doing hyposensibilization therapy? No reason to go the way of surgery before trying that. Worked wonders for me and my array of allergies, dust mites among them.
I tried hyposensibilization therapy, and while it worked for seasonal birch pollen issues, it didn't work for dust mites, oral allergies, and chronically stuffed sinuses.
