No. Doctors can be so annoying when it comes to thyroid. I have had many wars with Gps and specialist and have shouted that i am not well. Then i was referred to mental health as the doctors thought i was crazy, but being referred to mental health was the best thing ever as mental health insisted on the right tests to be done and to be put on the correct dosage of thyroxine. Its thanks to mental health that i am well today. Please always go by your symptoms and not what the doctors say. Keep telling them your not well and something will be done.
What lab tests have you had done? If you could post the names of the tests and the results, that would be great. Don't forget to include reference ranges for each test because they vary from lab to lab, so must come from your own lab report.
The newly (8 yrs ago) recommended reference range for TSH is 0.3-3.0; however, even though this range was recommended by the AACE, many/most labs don't use that range.
The tests you should have had done, in order to get the best indication of your condition is: Free T3, Free T4, TSH. Just because you fall in the "normal" range on the lab report does not mean it's normal for your body.
If your actual thyroid levels are at the lower end of the reference range or your TSH is at the high end of the range; a really good doctor would be willing to give you a low trial dose of thyroid med to see if it helps alleviate your symptoms. This could be done very easily and would not hurt you.
All of that said, I can't stress enough, the importance of getting the proper testing done. Don't settle for Total T3 and Total T4 - those are considered obsolete and of very little value.
Maybe because your TSH and T4 levels are still within normal range. If they start you on something without needing it, it can really throw your body off and you might have a hard time getting it back to normal. My Thyroid meds constantly have to be adjusted, but ive been hypo for many years. Normal range for T4 is approx 4.5-12.5 and TSH 0.35-5.60. Its a possibility that your levels might be at the high or low end of the normal range, and that's why they are considering you borderline. Hope this helps.
