You mean the breast cyst is gone? How do you know it's totally gone? Did you have another ultrasound? I don't think that would have anything to do with Synthroid. I think it's just a coincidence that it appeared/disappeared when it did. It could reappear again at any time. I'd certainly agree that it should be checked again in a few months.
To answer your previous question... Cortisol can affect thyroid hormone levels and it's best to do cortisol as a 24 hr saliva test. Many doctors won't order this test and many insurance companies won't pay for it...if this is the case for you, we can tell your where to order it online for a very reasonable price.
If it's positive that you had/have Lyme Disease, why were you never treated for it? It only progresses if not treated. How did the EBV manifest? Did you have mono?
FT3 can be "upper half to upper third" - there's wiggle room there and some people go to the top of the range, as long as they don't have hyper symptoms. And yes, you want FT4 around 1.3. Of course, this is assuming that the lab you use continues to keep the same reference ranges.
Just keep in mind that the labs are "guidelines"... your symptoms are the deciding factors.
Note: You're saying "T4 and T3"... always make sure Free T4 and Free T3 are tested... I know that sounds nit-picky, but if you don't specify Free T4 and/or Free T3 or FT4/FT3, you'll get Total T4 and/or Total T3 and they aren't the same tests nor do they provide the same information as the Free's...
I'm confused as to why you'd think you'd have to abandon the chosen avenue of treatment... once you find something that works, the last thing you want to do is abandon it. The only time we abandon a working treatment is if we have to change doctors and the new doctor refuses to prescribe the same medication or something like that... then we start looking for another doctor... lol
You're right, though, that you'll probably have to add a source of T4 in order to get/keep your FT4 at/near mid range - and remember, these are guidelines - you don't have to keep your levels "exactly" at 1.3 and 3.3... you aren't going to be able to do that as they will fluctuate at times - just stay in the ball park and feel well.
Don't forget to split the NatureThroid dose - 1 grain in the morning and 1 grain around noon... if you wait too late in the day, the T3 in the medication will cause interference with your sleep. If you have the med dispensed in 1 grain tablets, you won't have to split the pills.
Typically, it's best to test at 6 week intervals, as long as we're actively adjusting medication(s). Once you get to the point where you think you're pretty close to optimal (for you), you can cut back to every 3 months, then when you get there, every 6 months. My doctors have always had me test every 6 months; others have patients go for a year. I think a year is too long, but if you feel okay, it's fine as long as you can test when you need to. Always make sure Free T4 and Free T3 are tested every time... never settle for just TSH.
You can test female hormones and cortisol whenever you want to. It's a pretty sure thing you're in perimenopause; are you looking to supplement your female hormones? There are herbal supplements you can try, to help alleviate those symptoms, if you're interested in that route.
It's normal for the adrenals to kick in to take up the slack when there isn't enough thyroid hormones, but they should go back to normal soon. A single blood test is a poor indicator of adrenal status. The best test is a 24 hr saliva test. Not all doctors will order this test and many insurance companies will not pay for it. You can check it out and if yours won't we can tell you where to order it online at a very reasonable price.
Weren't you treated for the Lyme Disease? If so, that means you should no longer have it, even though it "could" have triggered your Hashimoto's. But then if you had EBV, so could that have triggered your Hashimoto's... They could both have been the triggers - who knows?
Is the one TPOab the only antibody test you've had done? that one isn't very high, since we often see antibodies, either, TPOab or TgAb, in the hundreds or even thousands.
Some research indicates that selenium will lower antibody counts; I've taken selenium for years and my antibody counts started going down when my thyroid died, but they still haven't gone back to zero yet...
Some people also say that you can reduce antibodies by eliminating wheat (gluten), and while some research is pointing that direction, it hasn't been proven yet. My doctor says "why do eliminate a food if you don't have to?" meaning there's no need if you aren't allergic/sensitive to it.
As for what you should do - you're the only one who can make that decision, along with your doctor, You have 2 options, which are the NatureThroid or the synthetics. It's not unusual for those on desiccated hormones to have to add a small amount of T4 medication, such as Synthroid or Levo in order to increase Free T4 levels, but, in my opinion, that's a small price to pay, if you feel better, overall...
If the osteopath is willing to prescribe what you want, personally, I'd go for whichever I felt the best on and stay with it until my levels were optimal. Once that were achieved, if symptoms weren't alleviated, I'd start looking at vitamin deficiencies, other hormone levels (reproductive hormones, cortisol, etc).
"I concluded that NDT was 'not working' for me, that I am not a candidate. Was it premature to conclude this?"
Yes...but it wasn't only the NatureThroid; it doesn't look like you've ever really had a high enough dose of any type of thyroid medication to get your levels, to what we would consider, "optimal".
As I noted in my previous post, Free T4 should be about mid range, so if the highest you've ever been is 1.1, in a range of 0.8-1.8, the most you've been is 30% of range... that's not high enough.
For Free T3, you should be in the upper half to upper third of the range. With a level of 3.2, you would have been at 58% of the range... while that's in the upper half, that's not high enough for many of us, especially with Free T4 at only 30%.
You have to have a good balance of Free T4 to Free T3, which is why the recommendation of FT4 at mid range and FT3 in the upper half to upper third or range. If either are too high or too low, you aren't going to feel good; in your case, both have been too low.
Most of us find that when we take a thyroid medication with T3, such as NatureThroid or Cytomel/Liothyronine, it works best to split it into 2 doses, with 1/2 in the morning on an empty stomach and the other half around noon or early afternoon, since T3 is fast acting and only stays in the system for a few hours. This keeps Free T3 levels more stable throughout the day. I'm sure it must be difficult splitting a 25 mcg cytomel tablet in half to get 12.5 mcg, then splitting it half again in order to take 1/2 in the morning and 1/2 later in the day.
Both your Free T4 and Free T3 are way too low in the ranges. Free T4 should be about mid range and Free T3 should be in the upper half to upper third of its range...
That said, why did you decide to change from NaturThroid to synthetic when you were feeling so good? Why not simply increase your dosage?
Do you know what your labs are like on the 88 mcg Synthroid and 12.5 cytomel?
Did you take all the NatureThroid in one dose in the morning or did you split it into 2 doses? Had you taken your dose prior to having the blood draw?
Are you currently, taking all your cytomel at one time or do you split that into more than one dose during the day?
Are your symptoms mostly the depression, PMS type or do you have others, as well?
Sorry to ask so many more questions, but the answers will help us give you better responses.
