I am 22 years old , Male.
From 4 years ago I had this issues near my shoulder it looks like it line that link neck to the bone I just don’t know what to call it , However i have no pain in this area but i love bodybuilding and it just destroy how the body look.
I remember how i got it , it was from a wrong movement when i start bodybuilding I used a heavy weight while I was doing DUMBBELL SIDE BEND i should move hips when doing DUMBBELL SIDE BEND but i was using my arm not hips , the next day i notice it in a mirror.
