Since December of 2007, I have been trying to find out what is going on with me. I have a nodule on my right thyroid gland...they did ultrasound, normal, a biopsy, normal, and a thyroid uptake scan, normal, but I still have the nodule, and they can't figure out what is going on. Both blood tests I have recieved, my Free T4 has come back normal, but my TSH levels are very very low, almost non-existant. The one taken in December my Free T4 was 0.98NG/DL and my TSH was <0.06L mIU/L.
