PIC cant direct link? visualeditors.com/gude/wp-content/uploads/2007/10/karl-shoulder-injury.jpg 4 days ago, I went to the gym and did a couple of usual shoulder excercies. (row, lat pulldown). then i was moving some stuff around the house. I was lifting and lowering somewhat heavy/bulky things. the next morning, i noticed that the bump on top of my shoulder is sensitive, and slightly painful. according to the webpage where i got the pic, his collar bone separated due to fall. i have slight pain when i move my shoulder in certain directions. I will be making a doctor's appointment. but since today is Sun, i was wondering if u knew what it was.
