This morning I stepped on a thorn on my hallway floor and immediately thought about tetanus. (When people are in a hurry they will occasionally wear their shoes inside the house, so I assume that is how it got in here--my mother hasn't started gardening yet.) The puncture didn't cause any visible bleeding, which is a good sign, but I'm still anxious because I have never been immunized (stupid, I know). I've decided to set up an appointment with my GP tomorrow, but how urgent do you think this is? Though my OCD is surely playing a part, this is still very distressing.
