The first point is whether a chiropractor would be considered suitable medical advice or treatment. I strongly doubt their views would be considered a specific medical diagnosis of a specific condition (seeing as some claim "spinal misalignment" can cause asthma).
If you're experiencing discomfort, you'll need to see your GP and then a consultant.
If the accident wasn't your fault and the consultant diagnoses an injury caused by the accident, you would be entitled to getting medical expenses covered.
