i was in an atv accident yesterday, i felt a sharp pain in my back but i could walk and move fine. this morning i woke up and could barely get out of bed. i went to a chiropractor's office where they took an xray of my back and they said the last piece of my spine was out of place and some people have it and never know... but they did not tell me what to do about the pain or what is causing it and how long it will take to feel better? please help.
