It was particularly bad when the nurses would come and give you some notice that they were coming to change the bed sheets so click click 5 minutes later they turn up and roll you over to change the sheet and you just want to rip the farking heads of cause it hurts so farking much. After about the 4th or 5th day and the pain is starting to subside its not so bad. And this was when i was only 12 or 13.
