Help with my symptoms

[corr275]

My thyroid has been killed with radiation now for about 10 Years.  I still struggle with symptoms.  I am currently on Levothyroxine 137m.  

My levels are:
FT4   1.35      (Ref .58-1.64)
TSH    .11      (Ref .34-5.60)
FT3    3.23     (Ref 2.39-6.79)

Any idea as to how to treat the following symptoms?
Confusion and Memory (worry me most)
Overweight
Fatigue
Slow Speech
Joint & Muscle Pain & Stiffness

I am only 42 years old and I feel 100.  Please... can anyone help?

Thank you so much for your advice.  Actually my doctor has checked my Vit D and B-12 and has been treating me for both.  My Vit D has come up to 19.8 and my B-12 to 788.

I'd say that most of your problem is that your body is not adequately converting the T4 med to T3.  Free T3 largely regulates metabolism and many other body functions.  Scientific studies have shown that Free T3 correlated best with hypo symptoms while Free T4 and TSH did not correlate at all.  Even though your Free T3 is within the so-called "normal' range that does not mean that it is adequate for you.  The ranges are far too broad for that to be true for all hypo patients.  Many of our members say that symptom relief required Free T3 in the upper third of its range and Free T4 around the middle of its range.  In order to achieve symptom relief you are going to need a source of T3 added to your meds, and then adjust upward until symptoms are relieved.

A good thyroid doctor will treat a hypo patient clinically by testing and adjusting Free T3 and Free T4 as necessary to relieve symptoms, without being constrained by resultant TSH levels.  You can get some good insight into clinical treatment from this letter written by a good thyroid doctor for patients that he sometimes consults with after initial tests and evaluation.  The letter is then sent to the participating doctor of the patient to help guide treatment.  In the letter, please note the statement, "the ultimate
criterion for dose adjustment must always be the clinical response of the patient."

So you need to find out if your doctor is willing to treat clinically, as described.  If not you will need to find one that will do so.  

In addition, since hypo patients are also frequently low in the ranges for Vitamin D, B12 and ferritin, I'd suggest that you requests tests for those at first opportunity.
