Sneezing all day

It was 83 degrees this afternoon and I spent much of the day working outside, trimming bushes, etc.  I'm not sure what is in the air, but I have been sneezing all day and my sinuses are stuffed.  I did get my workout in at Iron Works and a 2.5-mile trail run at the park.  I was testing my pulled muscle and took it easy.  No problem.
