Hello. So a year ago I was in the marching band playing an instrument that was rather heavy and teaching preschool. I am small in size and only weigh105 pounds. I picked up on of my students and felt a pain in my lower rib. There was a bulge and a lot of pain. The bulge felt hard and moved slightly. I went to the trainer and she said it was a dislocated rib. Later I went to the emergency room and they did X-rays they said it was my cartilage around the rib. Recently it has been pulling out a lot ore and causing me a lot of pain. Is it actually possible that it is the cartilage or that it i something having to do with my spine and my rib cage?
