Nothing is a coincidence, not even falling off the trampoline!
Our middle son had a small trampoline accident a few months ago. Since it left him with a torticollis, we went to the doctor, but he couldn't find a fracture on the x-ray. We were then discharged, but the doctor called us again that evening and said he kind of had a "funny feeling about it" and asked us to get an MRI* just to be on the safe side.
