I think you will find this letter to be on interest to you.  The letter was written by a good thyroid doctor for patients that he sometimes consults with from a distance.  The letter is sent to the PCP of the patient to help guide treatment.

Note that in the letter the doctor states, "The ultimate criterion for dose
adjustment must always be the clinical response. I have prescribed natural dessicated thyroid for your patient (Armour or Nature-Throid). These contain T4 and T3 (40mcg and 9mcg respectively per 60mg). They are more effective than T4 therapy for most patients. Since they provide more
T3 than the thyroid gland produces, the well-replaced patient’s free T4 will be around the middle of its range or lower, and the FT3 will be high-“normal” or slightly high before the AM dose."

High levels of Free T3 can cause bone problems, but only if it's allowed to remain above range for extended periods, in which case, you would be considered hyper and would have hyper symptoms.  

Please post your latest thyroid levels, with reference ranges, so members can help assess your situation.  You need adequate amounts of FT3 in order to feel well.
