The hospital room smelled like stale ginger ale and floor wax, that sharp Pine-Sol smell that sticks in the back of your throat long after the bucket has left the room. My left hand had been doing a strange little fluttering thing since 4:00 in the morning, like a moth trapped under a glass, but I kept my thumb pressed against the mattress pad so nobody would make a fuss. Dr. Mehta had told me the night before that I needed two more days under observation. She was a small woman with sharp glasses and hair pulled back so tight it looked painful, and she had stood right at the foot of my bed and told me my blood pressure was still playing hide and seek.
