Sinus infection

I hardly slept last night.  Had a fever and chills.  I managed to get to see my doc this afternoon and told him that I was there for my annual sinus infection.  I started my antibiotics and some over-the-counter stuff.  For the second day in a row, I skipped Iron Works and went to the park.  I ran 2 miles on the park roads, but really felt tired.  I have a 5K this Saturday and a half marathon on Sunday.  Several years ago, I had a high temperature due to a sinus infection and ran the Dallas White Rock Marathon.  A friend brought me some of her leftover antibiotics to the start line.  I made it okay, but was a little slower than normal.
