Hi marriedtoLymeinNJ. I am on my way out. but I wanted to quickly respond to your post.
It is important to have the Free T3, Free T4 (besides the T3 and T4) and thyroid antibody tests done. These are blood tests. Many doctors do not run these and put too miuch emphasis on the TSH. In my experience, seeing an endo for thyroid is the equivalent of seeing an infectious disease doctor for Lyme. I have had more help from a general pracititioner. Hopefully the endo you see will be a good one. But if he/she is not, I can give you some suggestions.
