Shots

So I had to get three shots for my work trip to Turkey: Tetanus, Hep A and Typhoid. I don't mind getting shots, its never really bothered me. But when the nurse administered my last shot it sounded like it was spraying and i thought i felt the vaccine spreading after she pushed down on the plunger. It was totally weird. One arm had two shots and i cant lift it over my shoulders. I guess the spray sound isnt weird on Star Trek The Next generation every time Dr. Crusher administered a shot it sprayed.
