a form of similar pain (including movement vs still variation) that can come & go is also often in shoulder injury.

for me the hug feels like someone giving me an exagerated "bear hug" and just won't let go - sort of like a really wide bra strap that got tightened up and wouldn't release. Made it tought to get a good breath. I used to imagine "if I could ony lift up my ribcage and get a good inhale"

not "pain" but really uncomfortable with stabbing now & again. Not fun!
