are these levels dangerously low?

[soozzze]

I just had a call from my doctor who said my tests for my thyroid were normal but my TSH levels were 0.03. She also told me in 2006 they were 0.15 which is lowish...they never told me about this result. I am terrified and with the stress I already am under I am fearful of the levels getting even lower. My doctor said all my symptoms were not a result of the TSH as this alone does not cause symptoms!! My brother tells me different.
Does anyone know please?

I do have many symptoms which I would connect with hyperthyroidism, svt and chest pain, infections, skin probs, hair thinning, severe migraines (always had them but much worse now), unable to sleep, intense hot flushes and sweating, oh, loads of symptoms, I was told many times by my doctor it was the stress I am under......terrible pressure in my head too. Had shingles twice last year and four lots of antiobiotics to fight a severe sinus infection. I have MASSIVE stress levels, a lot going on in my life and little support but I know my symptoms not all stress.
I sound like a real complainer but I am scared and really need to sort this out, I do feel the docotrs see me as making a fuss.

ps. I have not been given any medication and am going to be re-tested in 6 weeks. In 2006 the TSh was 0.15 but they never told me there was a prob, I only found this out today. Thanks for all the information.

Thanks all for your comments. I don't have all the other results other than being told by my doc that the thyroid itself is normal and all my other test were also, there were 3 pages of test results (goodness knows what they were but I know there were Haemoglobin, platelets, white counts etc) all normal apart from the TSH of 0.03.
I'll try and get a print out of the results tomorrow and post them. Thanks again.

Another general comment...your doctor is right; your brother is wrong.  TSH causes no symptoms.  TSH is nothing but a messenger from your pituitary to your thyroid to tell your thyroid to produce more T3 and T4.  Too much or too little T3 or T4 is what causes symptoms.  In a perfect world, TSH acurately reflects T3 and T4 levels, but once we've thrown us humans in there, the perfect world dissolves pretty fast, since many factors besides thyroid hormone levels affect TSH.  Your FT3 and FT4 levels are much more important.  Please post them if you have them or ask your doctor for them (with their reference ranges) as gimel suggested.

One general comment: ANY time you have lab tests done, get a copy of the report, so that you have ALL the numbers and ranges.  Your TSH does sound too low.  Mine briefly went too low when we were trying to adjust my synthroid dosage.  During that time I was quite "active" due to the overage of the hormone.  Look up the symptoms of HYPERthyroidism and see how many match how you are feeling.  If a lot match, you probably need further testing.  If your dr doesn't want to pursue it, find a new doctor.  You have to be your own advocate because most drs don't really understand the thyroid like they ought.

Please post the other test results and their reference ranges.  Have you ever been previously diagnosed as having a thyroid problem and given medication?  If so, what medication and how much daily?  Do you have any symptoms that you would associate with having a thyroid problem?  

Sorry for all the questions, but they are important to trying to answer your question.
