OK, so do I feel sick, or do I just think I feel sick?

I got a call from my doctor telling me I have to come in on Monday. Something about an elevated white cell count. If all goes well, it means I get to go in to find out I have a cold. And vigorous exercise is supposed to cause it as well.

I fell asleep in the middle of the day, and I’ve been feeling a little run-down. I’m guessing I not only have a bit of a cold, but my Sunday run may have been a bit too “vigorous.”
