a couple of months ago, i started noticing my right trapezius was bigger than my left. i thought, how ironic, i'm LEFT HANDED! and much stronger with my left. i write with my left, i do everything with my left except right handed mouse. a few weeks ago, i was doing bicep curls and i felt a tear in the left shoulder where it felt like my left arm got lowered from the socket and the pain wasn't major and it was gone within 2-3 days. i'm not sure if the bone on the left side of my shoulder is sticking out higher than my right or the ligament/tendon or whatever stretched/tore too far low thus why my trapezius is lower when relaxed and flexed. i was holding 2 70 dumbbells on each hand doing shrugs when i relaxed, i felt like the tendon/ligament or whatever stretched too far down and i felt a small pain on my left shoulder. it wasn't a rip or anything, it was like a reminder that there is something wrong with my left shoulder. i don't have shoulder pains or anything but i have had a few injuries to both sides of my shoulders from falling off rollerblades to a bit more extreme, getting hit hard in the shoulder hard in football resulting in a lower back injury.
by tommorow, my trap would heal and be on its way back from recovery from lifting but still, this protrusion of bone or sink of my trap will still be there but i won't feel it unless i lift heavy. what is this? uncommon?
i would go get an x-ray if i had health insurance but this does seem like something i would need surgery on in the long run if it's this weird looking i would think.
left trapezius is smaller or sunk. unflexed
closer up pic of left shoulder. bone protruding up or left trapezius just not holding my shoulder up?
right shoulder, normal.
