I’m sorry I have to ask a bunch of questions before I can give you an answer, so please bear with me. First we have to determine what your problem might be, then we can move on to the rest.
How long have you been hypothyroid/on Armour? Do you know what caused your original hypothyroidism? Were you ever tested for Hashinoto’s? That would be antibody tests for TPOab and TgAb.
What tests does your endocrinologist do on a regular basis? S/he should be ordering Free T4, Free T3 and TSH. Do you know if the antibody test, TSI, was done to diagnose your Graves Diseases?
Do you have current blood test results that you can post, so we can see where your results are within the ranges? Please be sure to post ranges with each result, since ranges vary from lab to lab and have to come from your own report(s). This would include, both, thyroid and antibody tests. If you’ve had an ultrasound, it would also be helpful for you to post those results so we can see if you have nodules that might be producing hormones, independently of the thyroid.
What ever information you can give us would be helpful, including any vitamin/mineral tests, etc., along with any other symptoms.
