Mustang8t4... I think, at this point, your doctor is trying to cover his rear, which is understandable. Do make sure you get all the right tests done.
In the meantime, a search for a different doctor might not be a bad idea, if that's still a consideration. 4-6 weeks is quite a while to feel crappy if there's a chance you might see someone else and get proper testing and a diagnosis in the meantime. Just something to keep in the back of your mind and mull over. I really don't think this doctor is going to do much to help you feel better even 4-6 weeks from now unless something earth-shattering shows up on either the ultrasound or the bloodwork.
Did the doctor say what he thinks might be found on an ultrasound or is he simply hoping to rule out thyroid by doing another one?
Retesting blood work in 4-6 weeks in reasonable, as long as he agrees to retest Free T4 and Free T3, along with TSH... Also get both of the antibody tests (TgAb and TPOab) done this time, as well since TPOab was not done before and under the circumstance, it certainly won't hurt to repeat the TgAb...
Hi... Sometimes if the thyroid is swollen (goiter), it can feel as though there's something pushing on the throat.
You said your ultrasound was negative for nodules, but how was that ultrasound? Nodules can pop up over time. I've even had them come and go. Do you have a copy of the ultrasound report? Sometimes the impression portion of the report will give information that tells whether there's inflammation in the thyroid or not. Inflammation can cause the feeling that someone is pushing on your throat.
Treatment with replacement thyroid hormones can often relieve the symptoms because it helps relieve the inflammation.
If you haven't talked to your doctor about it, you should...
Reynaud's is often a side effect of an autoimmune disease or a connective tissue disease such as a thyroid autoimmune disease, rheumatoid arthritis, lupus, schleroderma, cardio or other circulatory problems. I had Reynaud's years before I was diagnosed and it completely freaked me out! I still get it, usually in the winter, but I've been known to have it in the summer, too.
Mustang, your antibody tests are incomplete. You also need to test TPOab or thyroidperoxidase antibody. My guess with your low FT4, very low TSH, and the fact that you already have one autoimmune disease, rheumatoid arthritis, is that you might have Hashimoto's. Having one autoimmune disease greatly increases your chances of having another. I presented in a very similar way, and I have Hashimoto's. The lowest my TSH was recorded in the years before I was diagnosed was around .8, but it was not tested every year. TSH fluctuates, especially when you have undiagnosed and untreated thyroid disease.
I wish you a quick diagnosis, treatment, and recovery from your symptoms!
Now, back to business... yes, thyroid can cause the wrinkled fingers, but so can other things, including dehydration, magnesium deficiency, diabetes, and others.
In your case, I'd say there could be 3 possibilities for it: Reynaud's (even though it's summer, you can get the pruney fingers), thyroid, and dehydration.
Oops - I've just noticed that my on fingers are getting pruney... time to fill my water bottle again and see if I can down the whole thing before bedtime. :-)
I got an e-mail notification that there's supposed to be a post here about you having Reynaud's, but I can't find it... that's odd; I'm wondering if it will show up once I post as sometimes happens... I hope it does, so I can read the rest of your post.
If you mean some doctors will treat Free T3 of 2.7, you're right; good ones will, especially when one has multiple symptoms of hypothyroidism. Many are willing to try trial doses to see if it helps and if it does will continue prescribing to alleviate symptoms.
Think of it this way: most of us feel best with Free T3 between 50% and 75% of range... your Free T3 is only at 29% so you're falling between 21% and 46% short of what's recommended and been proven to help alleviate symptoms. That's quite a gap.
I'm assuming the heart rate at 60 bpm is resting? Normal is 60-100, so you're at the bottom of normal. If your heart rate isn't high enough, you won't get adequate oxygen to cells, which means, in turn, that you won't have adequate energy.
Hypothyroidism is known to cause swelling and/or puffiness around the eyes. Tiredness can also make it feel like the eyes are swollen.
Have, or would, you consider trying a different doctor? It seems to me that you might be beating your head against a brick wall with this doctor and he's going to keep you ill as long as your levels remain within the laboratory ranges no matter how horrible you feel.
TSH is a pituitary hormone and is an indicator, only... IT causes no symptoms. Symptoms are caused by the lack of, or overabundance, of the thyroid hormones, Free T4 and Free T3 - specifically, Free T3, which, as noted previously, is the hormone used by individual cells in the body... All TSH does is stimulate the thyroid to produce thyroid hormones. In your case, TSH of 0.231 is too low to stimulate your thyroid to produce adequate hormones to keep you going.
To answer your question, lack of thyroid hormones causes exhaustion and tiredness. Hypothyroidism also causes swelling/puffiness under/around the eyes... tiredness can cause that too, but when I was hypo, I had huge bags under my eyes and didn't even realize they were caused from being hypo until I got on medication and they were the first thing to go away... :-)
I hope your doctor ordered Free T4 and Free T3, this time, not Free T4 and Total T3, as he did last time...
I assume your heart function is being tested regularly since you've had a heart attack? Heart problems can cause the arms to feel heavy, tingly, etc... the low potassium can also be involved in heart issues (or I should say, heart issues can be involved in low potassium...). Again, the calf twitching can be related to the potassium issue. I can't stress enough how important it is to have the electrolytes balanced. Are you making sure you drink enough water? Dehydration can also cause cramps and imbalances in the electrolytes. Dehydration can also cause the crushing fatigue because we don't realize we're even thirsty until it's too late... We need to drink plenty of water throughout the day even when we don't feel thirsty. I keep a 20 oz glass bottle with me all the time - my goal is to fill and empty that bottle at least 3 times during the day and if it's really hot and I'm doing work outside, I'll aim for 4 times to make sure I stay hydrated. Many days I fall way short and those are the nights that I end up being awakened with cramps...
You could also try taking a B-12 supplement, since your level is less than optimal. Take a methyl B-12, which is one that's body ready so it doesn't have to be converted. A liquid, chewable or sublingual would be the best type to try. That could help with the fatigue, as could a folate supplement, since B-12 and folate work together and many doctors don't test folate.
I do agree that you need a doctor that is willing to look at the whole picture and can/will put it all together...
It's good that you're taking the vitamin D. You should get retested in a few months to make sure your level is coming up as it should. Sometimes as we get older we don't absorb it like we should.
I agree that your problem sounds endocrine - thyroid, adrenal, pituitary, hypothalamus, pancreas - all endocrine.
Potassium is one of the electrolytes, along with sodium, chloride, calcium, bicarbonate, magnesium. They're related to numerous processes in our body, including our heart, bones, muscles, nerves, etc. If they aren't balanced we can have heart attack, weak bones, muscle spasms/cramps and any number of things.
Prolactin is a pituitary hormone that's related to reproductive/sex glands. Low levels are often linked to sexual disorders and/or psychological fluctuations.
Oh my, sometimes things don't post like they're supposed to and we lose something we've spent a long time writing. I'm sorry if that's what happened to you. I'll report it if it did.
Okay... so it looks like your sodium levels are pretty low and your potassium, as you see is below range. That could very well account for the calf pains/cramps. Try eating more food that's high in potassium, such as baked potatoes with the skins. Medium baked potato with the skin has more potassium than a banana. Other high potassium foods include avocados, spinach, beets, bananas, white beans, swiss chard, tomato sauce, oranges, yogurt, clams, salmon, etc... it's not a good idea to take potassium supplements without your doctor's okay because too much potassium can be life-threatening. Low potassium can also be dangerous, so I'm surprised your doctor didn't catch that and discuss it with you; that was one of the first things my doctor picked out of a multi-page report that had quite a few other abnormalities...
What time of the day was the cortisol sample drawn? Was that a morning, fasting sample? Cortisol should be the highest first thing in the morning as we're preparing to start our day, then diminish as the day goes on and we're winding down to get ready for sleep... You seem to have a problem there but the most accurate way to test cortisol is via a 24 hr saliva test. This is 4 samples taken over the course of a day - morning, noon, afternoon and night. Most doctors won't order it, but I can tell you how to order it online without your doctor's order. The problem is that insurance doesn't cover labs ordered online without a doctor's order... A lot of people can't do that and that's understandable.
Your vitamin D is way too low, even though it's "in range". Vitamin D should be, at least 50, but 60-70 is better. Are you supplementing to bring your level up? If not, you should.
It's good to know that you're negative for thyroid antibodies and no apparent thyroiditis - that means you don't have Hashimoto's and points even more toward Secondary hypothyroidism as a cause for your low TSH and Free T4.
Again, I'd recommend talking to your doctor about that possibility and if he won't listen, it would be time for a different doctor - at least as far as I'm concerned. And don't forget to insist that you get the Free T3 test, along with the Free T4, also...
Okay... that's not really all I needed to know but I can make it work, since I've used Labcorp in the past, myself, though I've never known them to not put ranges on a report... but that's okay.
Going by the ranges they, typically use, your Free T4 is only at 31% of range, which is not nearly high enough. Most of us feel best with Free T4 at mid-range or slightly higher... In addition, your Total T3 is only at 22% of its range. Most of the T3 in our blood is bound by protein and can't be used, which is why we test Free (unbound) T3. Considering how low your Total T3 is, we can assume that your Free T3 is equally low, since Total T3 includes both, bound and unbound T3
With TSH as low as yours, we'd expect your Free T4 and T3 to be much higher than they are which would indicate hyperthyroidism... because of the low Free T4 and T3, which indicate hypothyroidism, we'd now have to suspect Secondary hypothyroidism which means that the thyroid probably works fine but there's a problem with the pituitary/hypothalamus axis so there isn't enough TSH being produced to stimulate the thyroid to produce the thyroid hormones... Doctors often miss Secondary hypothyroidism because they only look the TSH instead of looking at the Free T4 and Free T3, particularly, Free T3 which is the hormone used by individual cells in the body.
Your prolactin level is also lower than normal, further indicating a pituitary issue.
Your B-12 in the normal range, but it's not really optimal... most of us do best with B-12 at/near the top of the range. Some countries consider anything below 500 as deficient, so yours would barely be adequate.
Your magnesium looks good, but just testing a blood magnesium isn't really accurate. They should do an RBC magnesium; most doctors don't do that though. I know mine didn't - not even my naturopath.
Your glucose was in the normal range, when you had the blood draw, but some people don't do well with it that low; you could be one of those so blood glucose could still, partially, account for your shakes, weakness and the hot feelings if they come and go, like a hot flash. I have hypoglycemia, but my fasting glucose levels are almost always in the upper 90's. It's usually after I eat something that's sweeter or has a lot of carbs - in other words something that increases blood glucose - that I have trouble. What happens it that glucose levels spike, then suddenly, the bottom drops out and I get that weak, shaky, feeling of being really hot. After a little while, my body starts recovering and gradually those feelings start to subside, especially, if I eat something that won't spike my glucose levels again... You might want to try to watch what you're eating and see if it correlates at all; it can be anywhere from an hour or two to several hours depending on what and how much you ate.
The calf pain, I'm going to assume, might be some type of cramps... is that right? Since your chloride is low, I'd have to wonder what the rest of your electrolytes were like... Take a look at your Potassium, Sodium and Calcium levels. Even though they're in range, are any of them really high in the range or really low? If they aren't balanced, especially, potassium or calcium, you can get those pains or cramps...
You said your CBC was high... do you mean RBC as in Red Blood Cell count? Or WBC as in White Blood Cell count? It's not unusual to have high WBC if you have high inflammation because white blood cells fight infections, etc.
Anyway, none of the possibilities I mentioned should diminish the importance of your low TSH and low thyroid hormones. Those need to be further investigated as to all the other things I mentioned because quite often we end up having more than one thing wrong and doctors often tend to try to treat one thing and stop there, thinking that will make us well and it won't. We have to fix our whole body...
Do you know if you've ever had a vitamin D or ferritin test? Vitamin D is necessary for proper metabolism of thyroid hormones. Ferritin tells us how much iron we have in storage. Again, many doctors will look at RBC, hemoglobin and/or hemocrit and if those are normal, they think we're fine, but that's not the case. We need adequate iron for conversion of the Free T4 hormone to the usable Free T3 hormone.
That brings me to the last, but certainly not least point for right now... You should ask your doctor to test Free T3, not Total T3 because Total T3 is considered obsolete. As noted above, Free T3 is the hormone used by nearly every cell in the body and without enough, we will have hypo symptoms.
Your symptoms can often go with hyper, but many symptoms can "cross over" and apply to hypo or apply to other conditions as well.
You should ask for a thyroid ultrasound and talk to your doctor about the Secondary hypothyroidism as that correlates best with low TSH and low Free T4/T3.
Before I can really answer your questions, I have some of my own to ask you, first... When you had the first TSH test, was that all that was tested? What are the reference ranges for the Free T4 and Total T3? Ranges vary from lab to lab and have to come from your own report. Have you ever had a Free T3 test instead of a Total T3?
Have you had any antibody tests done to determine if you have an autoimmune thyroid condition? Both your symptoms and TSH indicate hyperthyroidism, but your Free T4 doesn't really correlate with that; neither does your Total T3, judging from rages we typically see, but of course, we'll know more once you provide the ranges from your own report.
You say your B-12 and folate are "good"... please post the actual levels with reference ranges, since simply being in range isn't always good enough.
What type of panel did you have done... There are a lot of them, so it's necessary to know which one you had.
Have you actually tested your blood sugar when you get shaky, weak, hot feeling to make sure it's not caused by low sugar?
