I was dancing this past weekend... I wasn’t dancing wildly or doing anything to strenuous... and suddenly I FELT and HEARD a POP in my side/hip area!! It felt like someone had kicked me in my side!! I've taken Aleve, 800 MG Ibuprofen, soaked in the bathtub with Epsom Salt.. nothing is helping. What could I have possibly injured??

Side/hip isn't specific enough, but first thought is hip dislocation, but you shouldn't be able to move at all. Second thought is crack in pelvic bone. Third is cracked rib. In any event, get to a clinic or ER for X ray.
