Hi, mrsD:

I thought T4 and levothyroxine were two different thyroid hormones. Thanks for correcting me.

To find the right dosage of levothyroxine for me, my primary care physician just needs to have the thyroid blood test results for TSH? He does not need to re-test other thyroid hormones and antibodies?

Quote: "Many people have their regular doctors take care of thyroid issues. Only extreme problems typically end up at the endo."

I am sooo glad I do not need to return and consult my ex-endocrinologist because he does not want to help me. I could be dead for all he cares. My primary care physician is really different and much better than this ex-endocrinologist.

Apart from thyroid cancer, what kind of "extreme problems typically end up at the endocrinologist's"?

How often do you have blood tests to see if your levothyroxine dosage needs to be adjusted?

Quote: "You should read up on this. Anyone on thyroid could use some back up learning."

I do a lot of research on the Internet about thyroid problems, their causes, their treatments... I do not have access to thyroid books because I do not have a credit card to order thyroid books from amazon.com. I miss the time when amazon.com used to accept bank checks.

I do not even know what kind of thyroiditis I have. My primary care physician did not mention anything about this, so I guess he does not know what kind of thyroiditis I have either. So it is hard for me to do the right research when I do not even know what kind of thyroiditis I have.

If you are tired of answering my questions, you do not have to answer them. You can just ignore them. Right now, I feel some really big depression and anger coming on into me because of my RSD and thyroiditis. Maybe I will post in the Suicide thread, as Chemar mentioned. Thanks for all the information you gave me.
