Your recent lab results are terribly low. No wonder you have bad symptoms. Free T4 should be around the middle of the range, at minimum, and Free T3 should be in the upper part of its range, as needed to relieve symptoms. What was the med and dosage before and after the switch to NDT?
A good thyroid doctor will treat a hypothyroid patient clinically by testing and adjusting Free T4 and Free T3 as needed to relieve symptoms, without being influenced by resultant TSH levels. Symptom relief should be all important, not test results. You can get some good info from this link. You might need to give a copy to your doctor and ask to be treated clinically, as described.
Hypo patients are also frequently too low in the ranges for Vitamin D, B12 and ferritin? If tested for those please post results. D should be at least 50, B12 in the upper end of its range, and ferritin should be 70-100.
Was the reduction a mistake, or what was she thinking? Even on the 1 /2 grains your Free T4 and Free T3 were too low.
Now that you are back on 1 1/2 grains I expect that it will take the same 3 weeks to get back to where you were previously, which is still too low of a dose. You need to read at least the first two pages of the link I gave you and give a copy to your doctor and try to get her to agree with treating you clinically, as described. If she resists, and only wants to pay attention to TSH levels, then you will have to push her to read and accept the suggestions in the paper linked above. If she refuses to change then you will need to find a good thyroid doctor that will do so.
Your D is way too low. I suggest supplementing at least 2000 IU of D3 daily. You also need to find out your B12 and ferritin and cortisol levels.
I assume that the saliva test is the four panel test with sampling at 4 different times of the day. When you get the results we have some experience with that and would be glad to help interpret and advise further. Note that just being within the reference range does not always mean adequacy.
What was your ferritin level? Also, you should consider supplementing your B12 with about 1000 mcg of B12 daily.
Your Free T4 and Free T3 levels were way too low even when you were originally on 1 1/2 grains of NDT. After your doctor erroneously cut your dose in half, your results three weeks were terribly low. Now you have gone back to the 1 1/2 grains for only about 12 days, which is not long enough to even get the full effect of the increase, much less get your levels to where they need to be. Since numbness and tingling of the hands and feet is a known symptom of hypothyroidism, I would suspect that as the cause, and request a further increase. If the doctor resists, point out that your levels on 1 1/2 grains of NDT were inadequate previously, even before your dose was reduced.
Since B12 is also a known cause of tingling of the feet and hands, I would make sure to supplement with 1000 mcg of that also.
You did not reply to the question about your ferritin level.
From your treatment so far, I expect that you will need to find a good thyroid doctor elsewhere. What cities/towns would you be willing to travel to? Perhaps we could help finding a good thyroid doctor? Also, what insurance coverage do you have?
Before going further with our discussion, I need the answers to two prior questions. What was the actual result for your ferritin test? Second, please name some cities/towns that you are willing to travel to in order to try and find a good thyroid doctor.
IF your last ferritin was high, it would be a good idea to get a full iron test panel done, if you can arrange it: ferritin, serum iron, TIBC, and % saturation.
I am sending you a PM with info on a doctor in Bangor that is regarded as a good thyroid doctor by patients. To access the info, just click on your name and then from your personal page, click on messages.
