If they state that I signed a Refusal to Care would I have been given a copy of that upon leaving jail the next day?

I am new to Florida so I'm not entirely sure if this applies. I had been out one night, had a few drinks. I was rear ended very badly by another driver who was not abiding the speed limit. It has been 3 days since the event and I have started having very bad pains in my head, neck and back. I was not brought to a hospital after the event by the police. I do recall prior to the accident but not immediately before or after. It was my understanding that in a bad accident, whether the person says they are okay or not they are to be brought to a hospital to make sure 100% that they are okay i.e. not concussions or internal issues. Do I have any case at all for this? In addition, if they state that I signed a "Refusal to Care" would I have been given a copy of that upon leaving jail the next day?
