My thyroid does not function and I just found out a year ago. I had my Internal Medicine doctor, and he just gave me check up orders for the T3-T4 tests and they all used to come out normal. I finally went to see an Endocrinologist, and he ordered a blood test called TSH and a thyroid sonogram, and found out that my thyroid does not function and that I have Hashimoto`s thyroiditis. I am now well, with medication (synthroid). I was always tired, nervous, and had gained weight also.
Hope this information is of some help.
A LITTLE ABOUT ME:
I am 63 years old, retired from the government and live in Puerto Rico.
