Feel like a wish bone being pushed together instead of pulled

My back has been killing me since monday Night. I have no idea why, my whole spine is is massive pain also with my rib cage. I feel that my rib cage is being forced to close in. The only way i can really explain it is with a wish bone. You know how you are suppose to pull a wish bone apart to make a wish? Well I feel like somone is pushing the wish together to watch the bones crush. I have went to the doctor and all that that they told me was that when my friend pushed me the force went down to to my rob cage and my back. I think that is total bullspit. I wake up at 3am crying and wanting to scream, all of this pain is not from a little push. What is wrong with me? How come I am in so much pain? In order for the pain to stop I have to arch forward or sit with my legs crossed and my head in lap. I hate being in this much pain, I really wish it would stop. Please help me. :'(
