Confusion Reigns

Did I tell you I slipped on the ice, fell flat on my back, and cracked my head on my cobblelock driveway? Such are the hazards of home improvement. It's a worry. Now, like a good hypochondriac, I am fretting that the dizziness (remember Enya?) may come back - after all a knock on the head was all the doctors were interested in at the time. It's been 5 days. You reckon I'm safe yet?
