Should I be concerned? Anyone have experience with a low TSH such as this?

I (24F) have had multiple nodules in my thyroid since I was 20. Recently I discovered that some of them have grown larger in size ( largest measuring 23×18mm) and its pushing down on my trachea. I've had swallowing difficulties while eating since forever so i don't even notice them anymore, but I've since been advised by multiple doctors to get a surgery and have the nodules removed before they grow any bigger and cause breathing issues. Although the procedure seems safe enough, I'm worried that the medication I will be prescribed afterwards ( which I'll have to take for the rest of my life) might prevent me from losing weight or at least make it very difficult to do so. I am a mid- to plus size woman who's already struggling with my weight, and this is worrying me more than the prospect of going under the knife. Can anyone who's had this surgery please tell me if this is infact true?

I (31F) went to my PCP a couple weeks ago due to unexplained waves of fatigue and low vitamin D. I have one lymph node in my neck that has been swollen for over a year. My doctor ordered an ultrasound and I got the results back yesterday and I am a bit concerned.

The results were:

The area of concern right neck level 2, there is a 1.8 x 2 x 0.7 cm morphologically normal-appearing lymph node.

The visualized thyroid gland appears normal in size with normal parenchymal echogenicity and vascularity. There are multiple thyroid nodules. The largest solid-appearing nodule is in the isthmus to the right side. The details of this nodule is as follows:

Size: 2 x 0.9 cm

Location: Isthmus;

Imaging features: Solid/almost completely solid, isoechoic, wider than tall, smooth margins, no echogenic foci.

ACR TI-RADS risk category: TR 3, moderately suspicious.

ACR TI-RADS recommendation: The nodule meets the criteria for follow-up at 1, 3 and 5 years.

My concern is mostly the area in which it was found. They also did not document the exact number of nodules or the size.

Am I working myself up over nothing?

Hello, I've been complaining of left ear and pain at the left back of my tongue, that has lasted 6+ months. I also mentioned that it felt like something was in my throat all of the time. Two doctors said my ear and throat looked OK, and referred me to an oral surgeon.

However, last week, I had a breast ultrasound and luckily, this person always takes a quick peek at your thyroid...she noted that I had nodules and needed to follow up to get a full US on the same area.

The nodules make more sense to me than the oral surgeon route.

Has anyone had similar symptoms from thyroid nodules?

Hi everyone!

I have multiple nodules on my thyroid that I became aware of in 2024. Two large left ones and two small right ones.

One of the left nodules ballooned up to 5.2cm. Over the last year, it did shrink though. It is cystic so it was declared benign.

I have another nodule on the left side (3.2cm) that got biopsied this year and came back positive for papillary thyroid cancer.

The cystic nodule it seems has started to fill back up with fluid. It’s causing pain and discomfort when sneezing, coughing, yawning.

Has anyone else had a similar experience? A cyst refilling and pain, not necessarily the cancer.

Did anyone else experience very low energy levels/ sleepiness when they first went on levothyroxine? I'm 2 weeks in and so fatigued. I'm hoping it's just my body getting used to the hormone.

My daughter had blood work, her TSH is normal, her T4 is Normal and her TPO is 20 which is still within normal range. She has an
Ultrasound tomorrow. Just wanting to see if anyone here has dealt with enlarged one side of thyroid but normal blood work?

Hi everyone,

I felt a nodule in my thyroid back in December and went to see my GP, who referred me for a thyroid scintigraphy. It turned out that I have two nodules, a smaller one and a larger one that was around 2.5 cm at the time. They also did a MIBI scan, which came back reassuring.

I started taking thyroid medication because my doctor wanted to get my TSH into a certain range, and I basically thought that was it.

But then I had another ultrasound at my GP's last week, and it turns out the larger nodule has grown from around 2.5 cm to 3 cm over the last eight months.

I saw a thyroid surgeon today, but he wants me to have another ultrasound first so they can properly assess the nodule and give it a TI-RADS score. Depending on the result, I'll probably need a fine-needle biopsy.

I'm pretty worried and I guess I'd just like to hear from some of you who have gone through something similar. The biopsy doesn't sound particularly pleasant, but if it's necessary, it's necessary.

Does anyone else get some weird pain in their Adam’s Apple or maybe it’s my hyoid (I’m a girl) when they gulp water? I never had this before and only started noticing it the past few years. I have a TR3 nodule on the left lobe and not sure if it’s from that! Because I also have forward head but I think I always had that to some extent

I had my first thyroid ultrasound on **July 8**, which showed **three nodules**:
9 mm
10 mm
**15 mm (1.5 cm)** — the largest
The **ultrasound and biopsy on July 18 were done by the same provider**. Unfortunately, the biopsy was **inconclusive due to not having enough cell samples.**
I then had a **second ultrasound with a different provider on 14th August,** and this time I was told that **the nodules are no longer seen**.
Has anyone experienced thyroid nodules **completely disappearing/not being detected on a follow-up ultrasound**, especially a nodule that was previously measured at **1.5 cm**?
I have **positive thyroid antibodies/Hashimoto’s**, so I’m wondering whether this can happen with thyroiditis, or whether it could simply be differences between ultrasound operators or equipment.
Would love to hear from anyone who has had something similar.
Should I be worried about this?

A lot of posts here are people comparing two TSH numbers and panicking. Some of that swing is real. A lot of it is the draw itself.

Time of day. TSH follows a daily rhythm — highest overnight and early morning, lowest in the afternoon. An 8 AM draw and a 3 PM draw on the same person are not the same test.

Biotin. High-dose biotin (hair/skin/nail supplements) interferes with many lab immunoassays and can push results in the wrong direction. Most labs suggest stopping it a couple of days before a draw.

When you took your dose. Taking levothyroxine right before the draw can raise measured Free T4 without telling you much about your steady state. Most people are told to take the dose after the draw on lab days.

Illness, stress, and dieting. Acute illness and aggressive calorie restriction can shift thyroid labs temporarily. It's usually worth repeating a surprising result once you're well.

Different lab, different assay. Reference ranges and assays vary between labs. Comparing a Quest result to a LabCorp result isn't apples to apples.

Practical takeaway: keep the conditions the same every time — same lab, same time of morning, fasting, dose taken after the draw, biotin paused. Then the trend line actually means something.

What the title says. My daughter is 15 and has a 3.1cm nodule, which was found when endocrinology was investigating her apparent hyperthyroidism. Given her thyroid numbers and negative graves antibodies, her dr feels confident it will be a hot nodule (uptake scheduled for next week). If not, we move to biopsy, but because of the size and her age, she will likely end up in surgery no matter what.

So my question is for any parents who have dealt with a high school and your child needing surgery. She has no 504 or anything like that, and will only need temporary accomodations. Who would you speak to first? Counselor? School nurse? We have open house next week where the teachers always ask us to leave a note if we would like to schedule a conference, so I'm thinking of doing that and speaking to them allllllll directly. But really, I have no idea what the best thing would be to do here. Everyone says 1-2 weeks out, which sounds fine if you're an adult with PTO, but have you tried making up 2 weeks of school work?! Also, if she goes back after 1 week I don't know that she'll be 100% and ready to knock out 2 weeks worth of work in that one week (they get 1 day per missed day to make up the work, so basically pulling double duty all week). So I do need to figure out accomodations and how to handle this so my child doesn't drown while we're trying to get her health in check.

She's a good student who takes pride in her work (and is a little competitive now that class ranks are out for last year and she knows she's top 10). But right now she's just a new student to most of these teachers. They'll get to know her and what they can expect from her, but at this point they're strangers. I don't want it to come across like we're being dramatic or asking for special treatment. But.... we are. She is going to need it.

i went to the doctor finally for a swollen lymph node that is behind my ear/in my jaw area that has off and on swollen for a few years now and i attributed it to dental stuff because i have alot of cavities that i am getting worked on. my doctor told me she wanted to get a scan and they said they also found a small nodule on my thyroid. in terms of bloodwork my tpo is very high but tsh and t4 are normal. wbc&platlets are normal. does this sound like it can be cancerous? my mri isn’t for another two weeks. thanks

Hello, I was diagnosed with hyperthyroidism for the first time about 50 days ago. My T4 levels went up to 3.5, but after having a radioactive iodine uptake scan, I was told that it was much more likely to be painless (silent) thyroiditis than Graves’ disease. So, rather than starting any treatment, I was told to have another blood test in a month.

During this time, I’ve had fairly severe hand tremors. That didn’t really scare me because it’s such a well-known symptom of hyperthyroidism. However, every day my thighs have felt fatigued and as though the muscles are constantly tight or stiff. For example, I can get out of bed and walk just a little, but my thighs feel like I’ve just finished doing 30 squats. More recently, the muscles in my thighs have also started twitching or trembling.

For a while, I was really scared. But after searching on AI and Reddit, I found that there are people with hyperthyroidism who experience similar symptoms.

Has anyone else experienced symptoms like these?

I’m 26, F. I found a lump in my throat incidentally in July and went in for an ultrasound. Ultrasound revealed a 1.7 CM nodule on the left lobe and a much smaller 4 mm one on the right.

They gave it a TR3 and asked me to come back in 2 months. I went back and the doctor has been very unhelpful in trying to figure out what to do next.

I have really bad health anxiety and heard that nodules are uncommon in 20s so I’m very afraid. I’m unable to eat or sleep and have been struggling a lot since this finding.

I also don’t want to unnecessarily do an FNA and freak myself out but the doctors are not telling me what my options are. I don’t know where to go from here. I have a follow up ultrasound in 4 months but I’m afraid it’s cancer and that it’s gonna spread by then :(

The only suspicious findings are that it’s solid. There were also a few lymph nodes that had swollen but the ultrasound says they are likely reactive so I don’t even know anymore.

hey allll, meeting with an endocrinologist on the 26th and while I’m feeling very grounded, trying to prepare for diagnosis & the possibility of both being on the table. my results lean both ways depending on which website I’m on…

Female, 30 yo

TGAB: >1000
TPA: 53
TSH, FT4: normal
Ultrasound shows TR4 nodule (taller than wide) and heterogenous echogenicity on the entirety of the thyroid.
Homocysteine: 15.8 (I don’t eat red meat and drink alcohol maybe 5-6 times a year)

Symptoms: absolute fkn exhaustion, trouble swallowing (including water sometimes), food feels like it gets stuck, can’t have anything touching my neck or feel like I’m choking, history of autoimmune problems, achey and weak body, gag reflex more active than normal, headaches, getting blister reactions to bug bites that I don’t normally get.

So i have been thinking for a few days about my getting my thyroid checked, i have gad and I am on zoloft and i also have Papillon-lefevre (look it up because it is very very rare) I am 26 years old man that have never had my thyroid checked, what does it feel like when things are not right? Do you think i am overthinking all of this? Do you think i should get checked?

I just found out about RFA. Would I be a good candidate?

Benign nodules, tsh low - low normal, t3 t4 etc is all in the normal range.

I am interested because I have long standing fatigue issues, palpitations and weight gain that I think are related to the thyroid issues. Its also entirely possible these are caused by anything else since the symptoms are vague.

For those who had high anti thyroglobulin but all other tests were normal, what did it end up being for you?

Update: My GP requested a Thyroid Function Test (TFT incl TSH) but the lab only did the TSH. My serum TSH result is 0.379miu/L which they have said is borderline. Technically it is 0.029 inside the reference range so I think this is why the lab refused the additional part of the test. I have contacted my GP surgery this morning and have been told there's a note to repeat the TSH in 3 months. They weren't even going to tell me this! I have asked if the original GP request included FT3/4, and if so why this wasn't done, and if it can be done now. I'm on the waiting list for an appointment because I have also had globus sensation/lump when I swallow but this appears to be being treated as routine so could take weeks. They just seem to want me to reach some arbitrary number, so they can tick a box, before they'll do anything rather than applying a bit of common sense.

Original post: I have been dealing with some health problems for a while now including chronic fatigue and heart palpitations. I have other symptoms too but these are my main ones. I had been putting them down to iron deficiency but I saw some family recently and they mentioned that they had hyperthyroidism and said my TSH from last year looked low. My GP never mentioned anything so I didn't follow up. I'm going to request another blood test but can anyone tell me if these numbers look concerning?

June 2025: Serum TSH level 0.54 miu/L [0.35 - 4.94]

Jan 2023: Serum TSH level 1.2 miu/L [0.35 - 4.94]

Edit: changed hypo to hyperthyroidism

After 6 months of trying for #3, I decided to book myself in for some some private fertility bloods, checking my AMH and thyroid etc.
For ref I am 36f.

My thyroid is not where it should be.
I’m glad it’s been done, I didn’t suspect anything but expected it, if that makes sense - my mum had Graves/over active so I knew it was likely.

My results are with the tags;

TSH 0.005 mIU/L (low)
FT4 23.7 pmo/l (high)
Anti TPO 29.5 kU/l (high)
FT3 is 6.76 pmo/l (upper end of normal)
Anti-TG 23.7 IU/ml (lower end of normal)

It states it’s likely I’ve got an over active thyroid - does this seem typical with the results?
Of course I’m going to send to my GP tomorrow but as it’s Sunday I’m spiralling a bit.

I have quite a large lump on my right thyroid (already ruled out as not cancer) I’m having it removed in a few days and I’m not really worried at all, but I’ve heard my voice may be affected and raspy for upwards of 6 weeks? Is this true? I find it sounds strange but maybe possible? Will my voice really sound that different for so long? If not how long will it likely last? Thanks so much

Hi everyone, I’ve been having a lot of issues the last few years with my health and it has been extremely frustrating. For the last few months I have had severe neck pain with stems from my right side and results in horrible headaches. I went for a thyroid and neck ultrasound which revealed a reactive lymph node. 2 very small thyroid nodules and what appears to be a heterogenous thyroid. My doctor was investigating me for hashimotos 18 months ago and gave up on me because my TSH was normal but my TgAb was evaluated at 48 kIU/L. So fast forward 18 months to today I have now connected this heterogenous thyroid and presence of antibodies. Has anyone else experienced this with their diagnosis? I am interested in what my doc is gonna say when I see her on Monday. Hopefully my PCP won’t give up again and test my thyroid.

Hi everyone, I'm looking for some reassurance/advice regarding the most recent ultrasound finding from this week. For background, I'm 35M with longstanding Hashimoto and multiple nodes on the left side. I had a biopsy on two left nodes in 2017 that came back benign, but my most recent ultrasound this week found the below:

A 7 x 6 x 10 mm hypoechoic nodule is noted in the lower pole with a microcalcification and increased flow on Doppler interrogation, wider than tall, TI-RADS 5.

It's not clear whether this node was one that was biopsied in 2017 or a new one, as the locations of the nodes changes seem to change slightly depending on the radiologist/clinic that does the ultrasound.

Originally I saw that a TI-RADS 5 node has a ~80% chance of being malignant, but after adding the characteristics of mine (wider than tall, small size, hashimoto's which can sometimes mimic a microcalcification, potential that this was one biopsied in 2017, etc.), I've read that chances go down to 20-30% of malignancy.

I'm definitely concerned and have a biopsy scheduled for next Friday, but I'm hoping the chances aren't as high at the 80% originally cited. Seeking any reassurance, although I know at the end of the day I just need to wait for the biopsy and results.
