Symptoms of Hypothyroidism

The Following quote is from ANSWERS.COM
"For some people, even if the TSH level is normal, or even in some bases, low normal, there may still be a situation where one is functionally hypothyroid, due to the body's inability to move convert circulating T4 thyroid hormone into the active T3 hormone at the cellular level, inadequate T3 hormone levels in general, or other factors. Inability to properly convert T4 to T3 can also result in fluctuating TSH, as the system struggles to keep balancing an out of whack T4 and T3 level, sending TSH levels up and down to compensate. For these patients, supplemental T3 may help them to feel well."

And the more I research the more I find out. this info i got from mayoclinic.com: Well, low TSH level can come from hypopituitarism in the pituitary gland. It can affect one or some of the hormones it secretes. And it can also be treated by several medications. one medication is Prednisone which I did take over the summer and felt soo much better. I tried to get my doctor to give me more but he wouldnt because its not good to stay on it. I still want an MRI because it can image the neck and spine in more detail, sometimes hypopituitarism can be caused by a tumor in the pituitary gland.

"Hypothyroidism due to low pituitary function: TSH-->Low T4-->Low T3-->Low(but to the right of T4) Temperature Pattern-->Low and very stable Commentary-->Looks just like primary hypothyroidism but TSH is low. We know there is demand because of high conversion of T4 to T3 but the TSH doesn’t rise to help T4 production." ~http://www.drrind.com/thyroidscalematrix.asp
