My g/f has a heritary condition where her arm isn't connected with the shoulder socket. She's popped it so many times that the tissue around it has worn out.

She's had surgery on her arm to put screws in but one of the screws kinda got loose and the top of the screw has been lodged in her arm. Not only did she have new screws put in, but they also did some stuff to the tissue to make it stronger. She also had that screw top removed and have another screw put in. Her arm was hurting for quite a while, so she won't be working for about a month.

I just back from the hospital, she's doing fine
