In addition to what everybody else is saying wshl, try doing slow-moving exercises, like stretching or yoga. This may increase the pain however. My mom had Fibromyalgia, not me, but I have broken bones, been shot, and have had cracked ribs before, and I got through the pain by not focusing on it. Play a video game, watch your favorite show, do something that makes you happy and consumes your thoughts and its easier to deal with the pain. The more pain you put out of your mind the less pain you feel. This is going to make me sound like a drill instructor, but pain is mostly in your head, you just have to put effort into not thinking about it
Feel better!
