If you were injured in an accident here in the state of Florida, then you should seek immediate medical attention, either with a doctor or at the hospital. It's also important that you seek prompt medical treatment. It doesn't necessarily have to be the day of the accident or immediately after the accident, but you should seek treatment within 14 days.
That's because under Florida Personal Injury Protection, under your own insurance policy, your insurance will only cover you if you sought treatment within the first 14 days of the accident. It doesn't mean that you can't make a claim against the other driver. It just means that in order to have your medical bills paid, you should seek treatment within the first 14 days.
