So I finally went to the doctor after a couple weeks of some serious pain behind my shoulder blade. I kept thinking it'd work it's way out but instead, it kept getting worse, waking me up at night and really bugging me.
Sure enough, the doctor said I had "lifted a rib" meaning my rib had popped out of place. She said it can be caused by moving something heavy, having a horrible cough with pneumonia, or lifting heavy objects.
Hmmmm...I'm thinking I know the culprit:The doctor said I needed to go get a massage to help pop the rib back into place. Doesn't sound so bad.
