General question, is it possible for TSH levels to fluctuate between hyperthyroid levels and within range? I was diagnosed with subclinical hyperthyroidism and multiple benign nodules, but my TSH levels are sometimes in the normal range for the lab I use.
Yes, it is. That is why folks on this board say that at TSH is minimally important. It's just not reliable. Focus on the free t4 and free t3 numbers...and if your doctor won't order them, find a new doctor.
