I am 37 years old, female. I discovered thyroid nodules in the mirror recently, large enough to see. Since then, I learned I have a family history of thyroid problems (grandmother had thyroid removed at ~40), my aunt also has nodules. I went to PCP and was diagnosed by palpation with nontoxic multinodular goiter.
Blood test results:
TSH 3.44 (0.450-4.500)
FT4 1.44 (0.82-1.77)
FT3 3.2 (2.0-4.4)
And an ultrasound (summary):
Right lobe: 6x2.4x2.3 cm. Heterogeneous with background diffuse nodularity. There are isoechoic nodules measuring up to 1.9cm. There is also a hypoechoic solid nodule posteriorly measuring 1.4cm.
Left lobe: 5.8x3.1x3 cm. Background diffuse nodularity. Solid isoechoic 2.2cm nodule with some internal vascularity, smaller nodule 1.4cm.
I saw an ENT for the first time today, and am awaiting scheduling for a fine needle biopsy (this is what I expected). I also asked them about hypothyroidism because a.) I have a few symptoms including periods of fatigue, weight gain (I've lost it now, but it happened), heavy/long periods, dry hair and skin, and I am cold all the time for probably last 20 years and b.) The ultrasound results state: enlarged thyroid and diffuse nodularity which from what I can tell is associated with Hashimoto's or an inflammation state (and not normal thyroid tissue).
The resident who saw me first basically said that my thyroid hormone levels are fine, that she's cold too, and I'm skinny so that's why I'm cold, and lots of things can cause those symptoms, and I don't have a family history of Hashimoto's and that they would know it if I had major symptoms. She said it's probably not Hashimoto's and even if it is, they wouldn't treat it because it's below their TSH threshold. I asked if the hormone could be fluctuating or has periods of hypo/thyroid growth, and got a "let's just focus on the nodules first" response, and was told to stop reading things on the internet. I agree the nodules need to be evaluated for cancer, but I'd also like to know the reason why my thyroid is so big in the first place (and if a thyroid issue is causing some of my symptoms).
The ENT doctor reluctantly wrote me an order to get the antibodies tested, probably for my peace of mind, but also told me that if it is Hashimoto's the doctor/pathologist doing the FNB will be able to tell from the tissue samples. I need to figure out where to go to get the blood test done or if my PCP can do it, and left the office feeling pretty frustrated with how they dismissed my concerns.
I just want to understand what is going on with my thyroid - if it is thyroiditis/Hashimoto's there may be things that I'm doing or eating that are negatively affecting the disease and causing nodule growth. I like to run, almost every day, and will often do a 2.5hr + run once a week, sometimes another 2hr run the same week - I've seen some websites suggesting extreme endurance (marathon running) negatively influencing thyroid function, especially in people with a genetic predisposition. Doctor and resident both said basically keep doing what I'm doing, but I have a feeling I may be destroying my thyroid with the long runs and not enough recovery time.
Has anyone else received a lot of pushback for trying to figure out what is going on or doctors being dismissive of their symptoms? I'm trying to figure out if I should just have the antibody screen done soon or wait until I get the results from the FNB - I'm feeling pretty negative about the whole thing right now.
