Thank you for your reply. I have since had T3, T4 tests.
T3 Free 3.6
T4 Free 0.8
It is my understanding all three of those tests are normal range.
I was unable to get an appointment with either local endocrinology departments, as they refuse to see me without tests showing abnormal results. I did however just get a call back in the last week from an endo that has a private practice, and will finally get someone to at least look at my issues.
Given the normal results I have given up hope that anything will come as a result, but at least someone is willing to look.
