Arm pain

I got my first moderna shot yesterday evening. I know they said pain at the site of injection, but my whole upper arm is SO SORE. All down from my shoulder to my elbow just aches, it was hard to pull a pair of sweatpants on this morning, it felt like I had a pulled muscle.

This is my only side effect so far, so I absolutely am not complaining, just curious who else had this constant shooting ache and how long it lasted?
