When you take thyroid med, within hours it spikes thyroid levels and suppresses TSH accordingly for most of the day. Although doctors don't seem to understand this, or ignore it, even the AACE/ATA Guidelines suggests that the morning dose of thyroid med should be delayed until after the blood draw for thyroid tests. I don't recommend taking the thyroid med before the blood draw.
As for your test results, if you took the Armour Thyroid, before the blood draw, then your results were falsely higher than reality. If you were not having any hyper symptoms at that time, why did you switch to Synthroid? Also, how much Armour were you taking at the time?
With your current med dosages, it appears your body is not adequately converting the T4 to enough T3. There is no magic ratio of FT4 and FT3. Your body uses only FT3. FT4 must be converted to FT3 in order to be used. Low ferritin is one cause for poor conversion. Ferritin should be at least 100. A good supplement for iron is Vitron C. A less expensive generic is sold at CVS, as Iron C. Each tablet contains 65 mg of iron. To raise your ferritin to 100 will probably require taking 4 tablets per week. B12 should be in the upper part of its range, so I think you would benefit from taking B12.
To alleviate hypo symptoms, you are going to need to adjust your dosages to get your Free T3 higher in range; however, if you are getting new tests for Free T4 and Free T3 on Saturday, I would wait to get those results before considering what the dosages should be. We will be happy to discuss further at that time.
One other question I should have asked before further comment. Did you take your thyroid med in the morning before the blood draw for those tests?
Hi Marina,
Please post your test results and reference ranges for FT3 and FT4, both current and when you were on Armour Thyroid. What other symptoms do you have? What are your Vitamin D B12 and ferritin levels?
Even the ATA/AACE Guidelines for hypothyroidism recognize the degree of fluctuation that TSH has over the day, and even from one test to another performed serially. TSH has only a weak correlation with either of the actual thyroid hormones, and a negligible correlation with hypothyroid symptoms. The only time TSH is useful as a diagnostic is when it is at extreme levels at which it indicates the likelihood of overt primary hypothyroidism. If diagnosed, TSH should never be used to determine thyroid medication dosage. Dosage should be adjusted as needed to relieve hypo symptoms, without going so far as to create hyper symptoms.
What other symptoms, if any, do you have?
Have you been previously diagnosed as hypothyroid? If so, what thyroid med are you taking and what dosage?
If not diagnosed, you should insist on being tested for both Free T4 and Free T3, along with Vitamin D, B12 and ferritin. Those are all very important to know for you.
If you want to confirm what I have said have a look at our paper on the Total Thyroid Process.

Yes, both elbows and top of one foot. I’ve heard of elbow pain in several of my friend's with Hashimoto’s. I don't know if it is when my TSH is high or low. It fluctuates severely.
I'm surprised that my Endo didn't even mention that it could be especially with my levels being so out of wack-for my last test results were TSH at .04
I have pain in my shoulders, albows, and wrists when I overdo it. Not always all at once. Overdo is a term I use loosely, as I am not working. If I could work, my whole body would feel like your elbow.
I always thought it was a result of being hyper for too long, not hypo. Could be wrong though. Happens all the time.
Tennis elbow and carpal tunnel are related to thyroid disease.
That is not to say it is the only cause of those conditions.
Your Endo should know that thyroid disease can affect joints.
