If you PM me a picture of it I can emit healing waves through the photo and to your left buttock, causing it to move back into place. I'm kidding, by the way. Please don't send me a picture of your butt.]
If a muscle has been torn off of the bone, please open a small entryway for the excess blood to spill out and carefully move and re-position the muscle back into place. If you do not feel like it is back in place, do another realignment until satisfactory. If you pass out from blood loss, please call a doctor.
