Prevent Sore Arm from Vaccination

After my first vaccination shot, a friend urged me to move and flex my arm. But that left me in an intellectual bind. What does "move your arm" mean? Do I watch the news, sipping tea with one arm while doing arcane David Byrne tribal movements with the other one? I did some haphazard arm waves and my arm was sore as hell for 2-3 days.

This time, I took it seriously. I went the full Byrne, right in the waiting room post-shot (half the room watched CNN, the other half watched me, but fuck 'em). I continued en route to my car. And I gave myself some booster arm movement before and after supper. Nothing obsessive, maybe 5-7 mins in total. Next day, my arm hardly hurts at all.

Do every sort of move you can think of. Pete Townsend wind-ups, extensions, bend at elbow while pushing back of head forward with your hand. Thermometer-reset-style shakes. Pet the full body of an imaginary very very large dog. Do all these moves with your hand/wrist/arm rotated left, then right, then centered. Do them fairly vigorously. The moves that hurt a little (in the shot area), do more.
