You may also want to keep track of what kind of pollen is really active when you are having these symptoms. There are a lot of websites for that, and you can also link to pollen count trackers through weather forecast websites.

You might notice a pattern where you have a sensitivity to a particular type of pollen -- in my case, trees or ragweed. Those are days when I will either take it easy or stay indoors if I must work out -- go to the gym or the pool. Generally I feel pretty crappy when those allergens are plentiful, so I usually just stay inside and try not to push too much.
