New ATA/AACE guidelines don't recommend FNA until the nodule is 2 cm unless it displays certain characteristics indicative of thyroid cancer. I have/had (??) a nodule that measures(d??) 1.1 X 1.0 X 0.8 cm and my pcp refused to refer me to ENT for FNA, even though it's a solid nodule, which is one of the criteria for cancer. He did order a nuclear medicine scan, which was a total waste of time/money...
My endo just did another scan and "she" says there is no nodule present... her opinion is that ultrasound technicians don't know what they're looking for and can't tell the difference between a nodule and a shadow. She says by the time the radiologist sees the pictures, the patient has gone home so they can't take another look, in which case they label it as a nodule, thereby erring on the side of caution. In her opinion, what the technician saw and radiologist saw as a nodule and what was again seen as a nodule during the nuclear med scan, was seen by my endo as a mere shadow...
The report I got from her says I have no nodule even though I have a chronic sore throat and often feel like something is stuck in my throat (she blew those off as "nothing").
Second opinions are always in order, in some cases as in mine, even a third opinion is called for...
My mother has low stomach acid and takes digestive enzyme supplements and also betaine HCL with pepsin (the HCL with protein meals).
Most guidelines recommend FNA (fine needle aspiration) biopsy for nodules larger than 1cm (larger than 5mm if patients has high risk factors or suspicious ultrasound features). I've read the overall incidence of thyroid cancer is about 9.2% to 13% in patients with thyroid nodules who undergo an FNA biopsy.
JCEM Journal - Postpartum Thyroiditis...
"Prospective studies have shown a prevalence rate of hypothyroidism of 23% and 29% at 3.5 to 8.7 yr postpartum (28, 29). Progression to permanent hypothyroidism was more common in women who presented with higher TSH levels and higher titers of thyroid peroxidase antibodies in the hypothyroid phase of postpartum thyroiditis (12). The development of permanent hypothyroidism provides further evidence that postpartum thyroiditis is the clinical presentation of preexisting subclinical Hashimoto’s disease (28)."
Autoimmune conditions tend to run in families, though not every member of a family gets the same condition. For instance, I have Hashimoto's and Pernicious Anemia, my son has Type I Diabetes and my daughter has Lupus - all autoimmune... Another thing is that once we have one autoimmune condition, the chances of getting another are greater.
Hashimoto's causes inflammation and that inflammation doesn't necessarily stay in the thyroid area; it affects the entire body, so your body aches can certainly be attributed to Hashimoto's/hypothyroidism.
It's not surprising that you, basically, feel like crap, looking at your Free T4 and Free T3 levels... Just because your TSH is where doctors love to see it, doesn't mean your thyroid levels are "perfect".
Rule of thumb (where most of us feel best) is for Free T4 to be about mid-range; yours is at 92% of range, which is considerably higher than it needs to be. Rule of thumb for Free T3 to be in the upper half to upper third of its range; yours is only at 25% of range.
Free T3 is the hormone that's used by almost every cell in the body and without enough, you certainly aren't going to feel well. Free T4 isn't used directly; it's considered a storage hormone and must be converted to Free T4 prior to being used. Not all of us convert adequately and when that happens we have to add a separate source of T3.
What was the "low dose" your endocrinologist recommended and are you still taking it?
Although postpartum thyroiditis can be diagnosed with high antibodies, there's a huge possibility that you have Hashimoto's, instead, which means it will not clear at all.
Is TSH the only thyroid related test that's being done, other than the antibody test? What about Free T4 and Free T3? Those are the actual thyroid hormones and are much more important than TSH, which is actually a pituitary hormone, not a thyroid hormone. In many cases, TSH doesn't even correlate with thyroid hormones OR with symptoms.
If you've been tested for those, please post the results, with reference ranges, so we can see what your actual thyroid hormone levels are.
I helped my acid reflux by drinking dill pickle juice, warm water with a small amount of vinegar and honey, taking peppermint oil pills, etc. I've also taken HCL with pepsin to increase stomach acid. I, too, have had H. Pylori.
Thyroid nodules are very common and less than 5% of them turn out to be cancer. Unless it was recommended that you get a biopsy, it's highly unlikely your nodule is cancerous. Nodules often reduce in size with adequate amounts of thyroid hormones.
I'd say all your symptoms can be traced back to your thyroid issues. For instance, both hypothyroidism and hyperthyroidism reduce stomach acid levels and this can cause a number of issues from vitamin B12 deficiency to H Pylori infection to acid reflux. Studies show patients with thyroid disease have a 1.7 fold higher risk for uveitis.
I've read post partum thyroiditis can take up to 18 months to resolve although some women will end up with permanent hypothyroidism.
