I have an extremely sharp pain in my right upper side of my hip, around the floating ribs on the side. When i laterally flex and bend backwards, it pinches hard and send a sharp pain throughout my lower right side. I have foam rolled it and done electrostim therapy, and nothing has made it go away. I was palpitating the area and it feels like a rib is sticking out or there is some kind of bump pressing out. I do not think it is anything gastrointestinal as it is on the surface of things and feels like a muscular problem. What could this be!?
