I saw my doctor today.
He recommended a nasal rinse.
Yeah, something like this.
It seems like an awful lot of effort, so instead I am using saline nasal spray.
So far it has helped.
I also ordered some Flonase from Amazon.
I'm going to use Claratin, Flonase, and the saline nasal spray.
My doctor doesn't think that I have bad enough allergies to get allergy shots, and I agree with him.
Thanks for the advice everyone!
