Doesn't hurt anymore when I breathe, it still does hurt when I twist my torso though. BBB, sorry for my lack of details, I'm not a verbally oriented person. IT felt like something was being squeezed, or maybe flattened, when the injury happened.
It hurt to move my arm, but it mostly hurt when I moved it backward, in a rowing motion, or when setting my arms up for the squat. The pain while breathing was short lived, a couple of minutes at best, and it only happened if I took a real deep breath with my chest. It doesn't hurt much anymore, but it definitely hurts the most when I twist towards my left side. Does that help?
