My chest has been hurting really bad. It hurts to breathe in deeply, bend over, push on it, etc. When I push on it it feels like I am pushing really hard on a bruise. It has only been a couple days since it started hurting but it just keeps getting worse. What could it be? P.S. could it involve being at my friends house and she has a 2 feet high rock wall and we were going full speed and the wheel on mine got stuck on a crack so I went down and I was lying on the ground for about a second but then it fell on my back. I was on the ground for about eight seconds with it on top of me on the ground with my chest facing the ground and the car/quad thing on my back. It hurt really bad. What do you think it is? I know something is obviously wrong and I need to know what it is and how to fix it so if you could tell me what you think, that would be great! Thanks!!
