I saw in your other post that you have had your thyroid removed. How long ago was that? Did you also have RAI or are you about to have it? Are you on any thyroid meds yet?
Your TSH is 89, and the normal range is now recognized as 0.3-3.0.
That TSH is quite high, and it indicates that you are hypothyroid and should have more testing. Ask your doctor to test free T3 and free T4. Those are the two thyroid hormones and are much more important than TSH. Once your doctor sees those, he can decide what further tests you need and can start you on thyroid meds.
A TSH of 89 is not going to do you in tomorrow, but it does warrant immediate attention. I imagine you must have lots of hypothyroid symptoms and not be feeling well at all???
