Good that he started you on meds.  He's correct that it's the least aggressive option and the only one that's reversible and won't leave you permanently hypo.

Inflammation of the thyroid can cause issues in surrounding structures.  The enlarged thyroid can put pressure on nerves.  

If you're very uncomfortable because of what is going on in your shoulders, neck and chest, by all means, see the doctor sooner.  However, I'd probably tend to take the methimazole for a while, which will reduce the inflammation in your thyroid, and see how you feel after that.  Until you've been on meds for a while, there's not much the doctor is going to be able to determine, except that you are hyper, which we already know.

august

but he called me and started me on methimazole

he said it was the least aggressive option, out of the three: Surgery, RAI, Meds.He wants to me see his partner at the office 6 weeks after fr a follow up and blood test

I came back from my massage and the lady noticed something in my shoulders and lower neck/upper chest (near collar bone) that didnt feel like a muscle knots.

Im thinking of maybe asking to see the doctor a bit sooner than 6 weeks. Is it possible that the thyroid could attribute to certain issues around the shoulder and lower neck as well? Inflammation?

You might not want to let this go until your doctor returns.  If symptoms went from mild to moderate that quickly, they could go to severe as quickly.

Yes, increased appetite, due to increased metabolism, is a symptom of hyper, as is weight loss or inability to gain weight.  

Any other symptoms, like insomnia, elevated BP and/or HR, hand tremors, anxiety, inability to sit still, etc?

doctor hasnt gotten back to me and it looks like I wont be able to see him, which *****. As for the tremors, its funny you mention that. Doctor asked me to put my hands up the last time I saw him, and he asked if i had any coffee. The updated my online record with tremor. I dont drink coffee as it puts me to sleep.

I have an appointment for a massage later today, to help with some stress, and shoulder/neck pain.

In the mean time, I'll just have to manage until he gets back.

His partner is in and I could see him but Im not sure there is an availability anyways. Plus, no one at the office seems to pick up as they are busier than a train station in NYC during rush hour.

Your TSH has continued to drop.  Labs will periodically change their reference ranges.  Different test kits have different ranges.  Many years ago, AACE recommended TSH range be changed to 0.3-3.0.  Labs and doctors, in the ultimate understatement, have been slow to adopt the change.  While your lab isn't quite there yet, they at least are moving in the right direction.

FT4 rose significantly in the eight weeks between the tests, from 56% of range to 77% of range.  I might call that a little more than a "slight" progression in eight weeks.  

How do you feel?  Are you having hyper symptoms?  Did you notice an increase in them between those two sets of labs?

everything went from mild, to moderate; as far as the symptoms. Basically, I barely noticed them in the beginning. Then it was very obvious. The shedding of hair from my body, and dramatic increase in bowel movements, were the obvious ones.

The weight fluctuation was already there. high 160s, to low 180 and back and forth. Its only recently, where I can not gain weight. In the last couple weeks, Ive been gorging on sweets, pizza, meat and weight is remaining in the low 170s, to high 160s.

I didnt realize how ferocious my appetite was, until I was told I needed to avoid certain foods for the uptake test. I just assumed I had a sweet tooth and loved pizza. That week of limited foods, pretty much confirmed my huge appetite must have been a symptom after all.

That tightness isn't uncommon.  Some people find that selenium helps relieve it.  If you take selenium, it can be toxic in too-high doses, so follow label instructions.  Brazil nuts, just one or two, also provide RDA of selenium.  

Well, of course, there is something abnormal; your thyroid is hyper-functioning.  Your doctor may be considering treatment or a referral, especially since he's going away.  

Have you had any thyroid blood work that shows where your FT3, FT4 and TSH levels are?  If so, please post with reference ranges.  Ranges vary lab to lab and have to come from your own lab report.

TEST 1

TSH .35 (range 0.5-5.0)
FT4 1.10 (range 0.6-1.5)
TEST 2: 8 weeks later
TSH .01 (range 0.34-4.0) same lab, different range. kind of odd?
FT4 1.29 (range 0.6-1.5)

doctor explained it as slight progression towards Hyper. Then tested Antibodies and all (except TSI wasnt tested) came back abnormal (slight elevation). Thyrogobulin came back within range but he said my Thyrogobulin AB could suppress thyrogobulin). Thats when he scheduled uptake and asked me to retest tsh and FT4. Also asked me to test TSI and FT3. Ive yet to do those tests as Im afraid insurance wont cover the tests in such a short time. SO Im waiting a few more weeks to retest.

Would you describe it as a feeling of fullness or tightness?

Odd there's no report.  Usually a radiologist will read it and give his impressions and then pass it along to your doctor.  I wonder if you called the imaging center, if they'd have a report that they just didn't put on the CD.  Your doctor's office might have it as well.

its tightness, like someone is pressing on the side of my neck. its located on both side and doesnt feel at all like muscle soreness or something you would feel if a little acid came up from your stomach.

its possible they didnt put the report in and I might need to request it. I'll call tomorrow and see what they have.

Also, I just received a VM from my doctor. I missed the call yesterday and for some reason my visual voicemail didnt update. Anyways, he says he wants me to come in. He never calls unless there something abnormal. Im thinking, he may officially have the report, but hes suppose to be leaving the country on tuesday, so not sure I'll see him in time.

Did you get a diagnostic report (text) along with the images?

no text. in fact the CD doesnt even have a result page or report page. Simply just images and copies of the documents that were filled out before the i123 uptake procedure.

Usually, the radiologist should explain things in detail? Id wait for my doctor to help with this but hes gone for a while and it could be a couple months before I know anything.

The odd thing about this, is that my neck feels a bit of pain. Different than simple muscle aches and different from acid reflux pain. Its a very off feeling and its constant. Not enough to hinder me from doing normal activities but enough to bother me.
Odd feeling* not Off feeling. Mistyped

That's the person who commented above.  If you'd like more comment, you might try PMing 898_1 and asking him to be more specific.  Just go to My MedHelp at the top of the page, choose Inbox from the drop-down menu and compose a message to him.

oh, I didnt know.

I was hoping for an explanation of the image itself. Can the person see nodules? Hot or cold? any abnormalities? Size of thyroid okay? Stuff a radiologist/radiodiagnotic can answer.

I'll msg the person and hope to see if they can help further.

Thanks again for all your help, its more help thn I received from the radiologist who did the test, who decided to just say "its hyperactive".

You guys rock!

The RAIU results show that your thyroid is functioning too well, i.e. you are hyper.  However, that could be due to  Hashi's as well.  There is often an initial hyper phase in the early stages of Hashi's, and some people swing from hypo to hyper for a while.  Also, Graves' can elevate TPOab and TGab a bit.  On diagnosis of Hashi's, both antibodies are often in the high hundreds, or even thousands.  I, personally, would consider your results borderline for Hashi's, and if TSI is elevated, I'd assume Graves' is raising TPOab and TGab.

Hello,

any chance the person who might be able to interpret the film, got back to you?

I sent a PM to one of our members who is good with imaging.  I'm sure he'll be able to answer your question if he's available.

Thank you to all who have helped.

Its possible I do have both as my labs showed positive for hashis, but my scan shows positive for graves? Of course TSI will make this more definitive.

Hopefully the person who can help with explaining the image, can chime in as well. Id like to know if I should proceed with an US and maybe a biopsy as Im guessing there is a couple small cold spots, among the hot spots (guessing from my limited knowledge on imaging)
Avatar universal
TPOab and TGab are both elevated, so it looks like you could be in the early stages of Hashi's.  Early stages can be characterized by hyper symptoms or swinging back and forth from hypo to hyper.  However, it is important to have TSI tested.  Although it sounds like an oxymoron, you can have both Graves' and Hashi's.  And Graves' can elevate TPOab and TGab as well.

Once again, imaging isn't my thing, but a google search revealed that SSN is the suprasternal notch, a normal part of human anatomy.  I can't really read the marker on the other because there's other text superimposed on it, but it looks like "R" to me...no luck finding that one.

Please post your antibody results with reference ranges.  TPOab was elevated?

thyrogobulin
33.2 ng/mL (0.0 - 55.0 ng/mL)

thyroid peroxidase autoantibody
70 IU/mL (0 - 35 IU/mL)

Thyroglobulin Antibody
31 IU/mL (0 - 20 IU/mL)

Muscle mass could be testosterone related.

Are you talking about the two glowing areas outside the thyroid (exiled perhaps?!) in the upper left image?  Imaging isn't my forte.  We have some people who really know what they're talking about with imaging.  Hopefully they'll be by soon.  

Have you had any antibody tests?

yes, the ssn and the one thats on the left (both circular).

what are they?
Ive taken all but 1 (TSI not taken yet) antibody test for the thyroid

thyrogobulin was high normal

the other two tests were abnormal

Avatar universal
The bright areas are the radioactive iodine glowing.  Your uptake result at 6 hours is 38.4 and should be 3-16.  At 24 hours, it's 48.5 and should be 8-25.

It appears you are hyper.  Is that consistent with your symptoms?

Yes, except for one symptom

My fat% is increasing
My muscle mass is decreasing

My weight shoots up (fluctuating) 10-15lbs in a week and goes down the same amount in the same time period.

If I press on area where muscle mass has decreased (hips, legs, chest, arms, shoulders); I get pain (similar pain to bruising) .

Not sure why my weight is fluctuating as it is and why my muscle mass is dwindling.
Also, what does the image mean? I see 2 (nodules?) just hanging outside of my thyroid?

Is like They are on the outs and have moved on to live elsewhere (humor)
No this is salivary gland and marker placed outside to calibrate uptake measurement
