There is an nasal cortisone that just went OTC (Over The Counter), it's called Rhinocort. I've been prescribed it in the past from an ENT. 

I've used Nasonex, Nasacort, Flonase with mostly good to mixed results, but as usually happens after time cortical steroids won't work well. 

2 weeks ago I spied the Rhinocort on the shelf at Carrs and gave it a try, it went OTC in February. WOW, it actually works and quite well.

 I use this stuff because if I don't I can get those kind of headaches where there is nothing to do but go lay down, long term headaches that can last several days. It takes 3-4 days, because of the nature of the drug, for the Rhinocort to kick in. But when it does the relief is the best I've had for a long, long time. 

This time of year with the pollen and dust from the Knik can really give me grief.  This year the pollen is really cranking along. Rhinocort is an unexpected but very nice relief!
