Shazam Shoulder

I've noticed that I adopt a very strange posture in the passenger seat of our Peugeot when the kids ask me to Shazam a track on the radio. I stretch forward to place my iPhone close to the speaker with my left hand, while tapping instructions to the music app with my right. I'm wondering whether medics are now being confronted with a bewildering new range of strains and injuries with no obviously identifiable cause.
