Hi there ~
Sometimes undergoing surgery completely relieves the condition as there is usually a small passage created by what is known as a deviated nasal septum
(DNS) that causes you to have excessive sneezing
, runny nose, mucus drainage
, stuffiness, swelling etc. However if you have gotten all kinds of imaging studies done including CT scan of the sinuses and your primary problem is allergies, I would suggest that you are probably on the right treatment for the condition. Please consult with your allergist to confirm or take a second opinion
I hope this helps. Take care and have a nice day !
