I use both Astelin and Nasonex spray coupled with mucinex, sudaphed, singulair, garlic, and zyrtec
-D. When it is really bad, I take the Zyrtec-D and sudaphed at the same time.I remember Allegra-D pretty much curing my problems, but it made my neck and back hurt so bad that I had to quit. Sinusbuster also helps some. Have you discovered your triggers yet? I think mine are being too hot, cold air, dust, and strong odors and possibly car emissions. Don't give up.
