immunotherapy and sinuses surgary

Hello,

I am currently undergoing immunotherapy for 13 months now (d. pteronyssinus, penicillium mix 5 grass sublingual)  but I haven't really seen any benefits as yet for chronic Sinusitis  and Polyps however have had improvement in my asthma. I have nasal polyps which were mostly all removed but of cause have returned. I use nasonex (am/pm) and antihistamine daily and of cause constant short causes of Prednisolone and antibiotics which only seem to last a short while.  I do am/pm salt water irrigation but still have constant infections. I am also allergic to Ibuprofen and Aspirin so I find it hard to treat the condition other then with prednisolone which I wish I could avoid.

Is there ever an end to this and is my last resort more surgery and do people ever seem to get any better. Also do people improve after additional drainage is created in the sinuses and polyps removed?

Sorry I must sound like train wreck. Thank you in advance
