To make absolutely sure, however, ask your doctor. I have seen several doctors because of a back injury. As background for potential litigation, I obtained copies of my medical records. According to these records, I was born four years before my father and seven years after my son, was injured two years before my actual injury, sought medical care six months before the injury and had X-rays of my ankle. Sounds like a real comedy of errors to me.
Someone desperately needs lessons in how to take a valid medical history.
I can understand a little confusion in any medical record, but the systematic foul-ups in yours take first prize. I suggest that you pack up your medical records and find a practitioner who will get the real story down on paper, with accurate dates. Sooner or later, those original doctors are going to make a gargantuan mistake. You don't want to be a part of that.
