Sick Again?

On Saturday before the snowshoe race when I got up in the morning I felt a tickle in the back of my throat. After the race I was hacking pretty good, but thought it would pass. Sunday and Monday I ran but my throat was soar and I had this dry cough lingering. Took Tuesday, weds off didn't get much better and I've been sleeping on the couch  coughing. So today I went to the doctor and got the standard arythromycin, but he was wondering if there isn't an allergy thing going on so I got a couple other things. So basically I don't know exactly what the problem is but I am on medication for allergies and an infection. So, hopefully one of those things will clear it up. 10 miler tomorrow.
