I think you're on to something here. Wife was vaccinated at the same time I was. She followed up with a couple sessions of chair yoga; lots of arm movement and stretching of arms. I sat and watched ball games, primarily moving my arm to devour snacks. She experienced no pain in her arm, and no other side effects. I had pain. After the next shot, I plan on trying...different snacks wink
