Police Officers get MP from constantly Sitting with a thick belt on. Nerve Irritation of the Nerve could have happened to you easily from sitting on the floor, it would go away in a few days just as well. MP for me went from the top of my though to outer side. Another condition that can give the same symptoms is Bursitis in the Hip joint, and would hurt much more than MP. It sounds like you are describing. MP is light touch only, Bursitis of the Hip hurts like Hell right away!!!! that other thing described.. had that, could easily be that too.
