Keep in mind, my mom had it removed back in the 1980s. How things were done medically were different in that era. The other thing was the specialist at first thirst my mom had thyroid cancer.
There are different thyroid problems out there. I have been taking thyroid medication since the 2000s, but it is not Hashimotos. My mom was not the only one with a thyroid problem. My dad takes thyroid medication for years although it is not Hashimoto's.
The nature of my thyroid problem symptom showed in two ways. I had chest pain and some of test readings were off due to my thyroid giving off a false reading. I had it checked by a doctor. I was concern with chest pain because at the time, I had relatives on both sides of the family that had heart problems without any idea that chest pain can be a sign of thyroid problems.
