am i sick?

I called my doctors office today from work. I was told that the doctor wants to see me again in his office.
WTF?
I didn't have the privacy or the time to question the person from his office that I spoke to. I planned on calling them back when I got home from work. But by the time I called them the office was already closed.
I'm back and forth between worrying myself sick and thinking it's probably just a little problem.
I'll call them again in the morning and find out what's going on.....
