Cedar season here is my worst pollen season (December through mid-April). I actually start feeling a little better in spring. Oak pollen is a problem and sets me back some, but in general spring is a little better for me. I can still tell when the pollen count jumps up though.
My chest has become heaver and it was harder to breath so my doctor increased my Advair to 500/50 which has helped I still have problems breathing especially when the tree pollen count is through the roof.
