Hi, You had trauma over spine region and following that you are having pain , restricted painful movement But you forgot to mention abut any loss of sensation or movement , bowel bladder involvement . So there may be having soft tissue injury or may have some bony injury as well. So u need a proper clinical evaluation including neurological status and accordingly need investigation like Xray of spine whole length in at least two views , CT scan , n MRI ALSO USG whole abdomen to evaluate and treated according to the diagnosis . So visit orthopaedic hospital esp spinal injury center (if available ) and befor that take analgesic (NSAID) , muscle relaxant , PPI ; apply spinal support belt , ambulation in log rolling technique . Hope this ll help THANKS N REGARDS
