Should I see an endrochronologist

I have had very slow metabolism, always cold, constipation, weight gain, intestinal problems, and more things that I have attributed to menopause or aging. My sister had the same symptoms and was finally diagnosed by an endochronologist with Hashimotos Disease. My doctor says his bloodwork indicates normal thyroid readings. I even asked about taking thyroid medicine (I was always told my thyroid was low and put on it during my pregnancies) but he said no that it could cause stroke if I don't need it. Should I bypass him and see an endochronologist?
